Not really "doable" for $200-$250. Plan to spend more.
You've bought a couple cheap tripods already, and found them unsatisfactory. You can either keep repeating that process or step up and spend some more, get a tripod that will do the job well and might last a lifetime. Compared to a continuous cycle buying cheaper tripods, you will probably end up saving money over time spending more now to get a good one. Besides, you're trusting it to support a couple thousand $ worth of camera and lens! So I'd recommend planning to spend more. Keep in mind that a quality tripod can last a lifetime (one of mine is about 40 years old... others are around 20 years old).
If I recall correctly, the 150-600mm weighs about 4.5 lb. Your camera probably weighs no more than 2 lb. So the combined weight the tripod head needs to support is under 7 lb. Rule of thumb is to buy a head and leg set that are rated for at least double or even triple the weight of what you plan to put on them. (Note: for the leg set rating, add the weight of the head too, along with the weight of camera and lens.)
Carbon fiber tripods can be a little lighter than metal. They also absorb fine vibrations better. However, CF also costs more.
For best stability get a tripod with as few leg sections as possible. Obviously, this effects how compact the tripod will fold up... so you have to find a compromise. While I think 2-section would be ideal, 3-section or 4-section legs are more practical. I wouldn't consider a tripod with any more than 4-section legs, though. The bottom segment ends up being awfully spindly and all those joints don't help with stability. They also are slower to set up.
Also for best stability, look for a tripod with sufficient height that you don't need to extend a center column (Two of my tripods don't even have center columns. A third tripod has one, but is an extra tall model that I never need to raise it... I use that
Check out a dozen different "Travel" Tripods in this article at B&H Photo:
https://www.bhphotovideo.com/explora/photography/buying-guide/travel-tripodsTravel tripods tend to be more compact and lighter weight. Likely the most stable on that list, the Gitzo is probably way more than you want to spend. The Benro Travel Angel Series 2 with V1E Ball Head that sells for a little under $400 is the model that impresses me the most, with: carbon fiber, 22 lb. capacity, 4-section legs (reverse folding), 66" working height (not sure it that includes raising the center column).
Also check out ten "Full Size" Tripods in this article:
https://www.bhphotovideo.com/explora/photography/buying-guide/10-recommended-tripods-photographySeveral of those aren't much larger or heavier than the Benro mentioned above. These tripods also are typically sold as leg set only, allowing you to choose your own head. For example, the Induro CLT303 leg set costs $399 (carbon fiber, 44 lb. rating, 3-section legs, 64" height), to which you might add the Induro BHD2 Ball Head for $179 (rated to support almost 40 lb., Arca-Swiss compatible quick release platform). Buying leg set and head separately this way allows you to select each item that meets your needs best. There are many other possible combinations from Feisol, Induro, Benro, Gitzo, Manfrotto, and dozens of other manufacturers. There are also kits of both head and legs that might save some money, so long as both items meet your needs well.
Other things to consider....
The leg locking method. There are basically three different kinds: levers, thumbscrews and twist type. On a tripod to be used in the field, I prefer the last because they are low profile... won't get caught on branches or cuffs as easily. They also are largely self-adjusting, resistant to dirt and aren't prone to wear. The lever type are faster to set up, but also are more prone to wear or breakage. The thumbscrew type are simple, but may be able to loosen and get lost.
Quick release... By far the most universal type is the "Arca-Swiss". Many manufacturers make parts and accessories compatible with it. You can even find lenses and cameras with built in A-S type dovetails (several recent Tamron lenses with tripod rings.... and the grips on some Fuji cameras). Even Manfrotto and Gitzo, both of whom have had their own, proprietary quick release systems in the past, are now making products with A-S system compatibility.
Gimbal heads... make using large telephotos like the 150-600mm a lot easier, especially when tracking moving subjects like wildlife or sports. Many gimbal heads simply replace any other head on your tripod. The problem is, to use it with the camera and shorter lenses, you'll need to swap back to using the standard head. A possible solution is to get a reasonably heavy duty ballhead and a gimbal "adapter" to use with it. That way you can quickly switch back and forth. Of course, there's additional cost to buy a gimbal adapter. But you could get a ballhead now and work with it... adding the gimbal adapter later. Here is a fairly complete guide to the different types and various brands of gimbals:
http://www.carolinawildphoto.com/gimbal_list.htm The Jobu "Micro" adapter would probably be fine with your 4.5 lb. lens. It's rated to handle up to Canon's 400mm f/4 DO lens, which weighs about 4.5 lb. The Micro is also one of the least expensive options. I've been using the Wimberley Sidekick for many years, with much larger and heavier lenses. Works great!
IF you decide to get a gimbal adapter now or plan to get one later, you
MUST use a medium duty (approx. 30 lb. rated) to heavy duty (50 lb. rated)
ballhead WITH Arca-Swiss quick release platform. The QR platform is how the adapter attaches to the head.... and allows it to be removed quickly and easily when you wish to use the tripod "normally". Together the gimbal provides the tilt axis, while the ballhead provides the panning axis.
I agree with Quixdraw's post... above... that, if possible, buying used can really help your budget go a lot farther. I bought two of my tripods that way and basically got them for close to 1/3 what they each sold for new! BUT, you really need to know what you're buying, have to be knowledgeable about the specific model tripod legs and heads to be sure what you're getting, especially if buying from an auction website (where there's a lot more selection, than shopping for used items locally).
Hope this helps. Have fun shopping!
