Thank you again for the advice and input. It is, again, greatly appreciated...
I was gonna ask, because it's hard to give very good advice without knowing what you wanted to shoot with the new lens and on what camera. Now you've given us some clues.
Assuming you are using one of the Crop There are several pretty good telephoto possiblities for sports/action/wildlife, without completely breaking the bank...
Sigma 120-400mm OS HSM... around $1000
Tamron 150-600mm VC USD... under $1100
Sigma 150-500mm OS HSM... about $1100
Canon 400/5.6L (no IS) USM... $1350
Canon 100-400L IS USM.... $1700
Canon 300/4L IS USM + 1.4X... lens: $1450, TC: $150-500.
Sigma 120-300/2.8 OS HSM + 1.4X or 2X... lens: $3600, TC: $150-500.
Another real workhorse for sports/action and general purpose is the 70-200mm. It's sometimes not long enough lens on its own, but for closer shots can be nearly indispensible. Still, it's easily my "Most Used" lens. Once again there are lots of choices...
Canon 70-200/4L USM (non-IS)... about $700 (w/o tripod ring)
Tamron 70-200/2.8 (not VC or USD)... about $750
Sigma 70-200/2.8 OC HSM... $1200
Canon 70-200/4L IS USM... $1350 (w/o tripod ring)
Tamron 70-200/2.8 VC USD... $1400
Canon 70-200/2.8 USM (non-IS)... $1550
Canon 70-200/2.8 IS USM (1st version, used)... $1500-1600
Canon 70-200/2.8 IS USM Mark II... $2500
I also know sports photogs who work with...
Canon 70-300L IS USM... $1600.
Canon 70-300 DO IS USM (very compact)... $1400.
There are some other, now discontinued lenses you might find used, that would work.
Except as noted, all the above are new prices from Amazon, and you might be able to do better elsewhere. You also might consider used or refurbished. If you buy used from a reputible dealer, lens will likely have at least a short warranty. Refurbished lenses sometimes have the same warranty as new. Look for refurbs at the Canon online store, Adorama and B&H Photo. Look for used with warranty from Adorama, B&H, KEH.com, and some other dealers.
All but one of the above lenses have fast ultrasonic focus drive, which is very helpful for sports/action/wildlife shooting. One of the Tamron 70-200s doesn't have their USD, so might not be fast enough focusing in some situations. (I haven't used it, so can't say for certain.)
Many of the above also have stabilization - Canon IS, Tamron VC, and Sigma OS. Some folks will tell you that stabilization isn't needed for sports, since you will "always" be using higher shutter speeds to freeze the action. I have been using stabilized lenses since 2001 and swear by them... especially longer telephotos. I have gotten shots thanks to IS, that I wouldn't have gotten or would have really struggled to get without it. And I don't always using high shutter speeds for sports (it gets boring, freezing the action all the time, in every shot).
Like you, I mostly shoot with a pair of 7Ds. The lenses I use on them the most for sports/action/wildlife are...
Canon 300/2.8L IS USM with Canon EF 1.4X II & EF 2X II
Canon 300/4L IS USM with Canon EF 1.4X II (handholdable)
Canon 70-200/4L IS USM
Canon 70-200/2.8L IS USM (1st version)
I bought the 300/2.8 and 70-200/2.8 new about 13 years ago (still shooting film then). The 300mm is going in for service (focus hunting issues... probably because it got a hard bump while we were bouncing around in the back of a 4x4 on a very rough trail, coming back from a shoot). I've never had even a hint of trouble with the 70-200/2.8. I use it a lot and it's probably taken close to a quarter million shots in the years I've owned it. Probably due for a "tune up". Eventually I will get the newer "Mark II", but I'm not in any rush.
I bought the 300/4L to have a lighter, handholdable, mobile alternative. The 300/2.8 can be handheld briefly, but ends up on a tripod for anything more than a few minutes shooting. Got the 300/4L used a few years ago for $900 (pretty much like new, off Craigslist from a private seller). I use it frequently with the Canon 1.4x II.
I picked up the 70-200/4 last year to have as a backup/loaner... paid about $900 for is used (also in excellent shape) with the OEM tripod ring (that normally sells new for around $150, tho there are cheaper clones).
If you got one of the longer zooms, you might be able to forego the 70-200.... But if you got one of the primes, you'd likely want a 70-200 to complement it.
The Sigma 120-300mm above lists the price for the current version. It's been introduced just within the past 6 months, or so. It might be possible to find the previous version, which also had OS and HSM, new for a few dollars less... Or used from someone who is upgrading or a trade-in. It's the priciest on this list, but is a very versatile lens that's usable with 1.4X or 2X teleconverters.
In most cases, I would not recommend a 2X on anything other than an f2.8 lens, but a 1.4X is usable on many of the f4 or faster lenses listed above.
Any lens or lens +TC combo that's less than f5.6 won't focus on your 7D. (There's a trick of taping up a couple the electronic contacts on the TC to make it try to work, just don't expect it to be fast.)
Personally I find image quality takes too much of a hit to use a 2X on most zoom lenses. The Sigma 120-300 is a rare exception. And the latest Canon 70-200/2.8 II and 2x III seem to work pretty well.
Of the above zooms, the Canon 100-400 is unique... It's the only "push-pull" design among the bunch. Some like this (especially for fast action shooting). Others don't.
