Regarding Costco... it appears to me that they offer pretty good deals on cameras, but only very limited choice and it appears
always only the cheapest possible lenses in their bundles. I have no personal experience with either the 18-55mm or 70-300mm Nikkors included in that bundle.... They're probably okay, but I wouldn't expect them to be great. They both are "AF-P" which are cheaper models that use a "stepper" autofocusing motor. Both those lenses use a plastic bayonet mount and both lenses have narrow manual focus rings. The AF-P models also don't have a switch on the lens to turn off VR (stabilization) if it's not wanted, nor do they have a switch for autofocus/manual focus. Both can be turned off in the D7500's menu, but that's not as convenient as a switch on the lens for these purposes. Neither lens has a distance scale either. As a result of that, there's also no depth of field scale, but those are only marginally useful on zooms anyway... especially on telephotos such as the 70-300mm.
Personally I'd prefer the higher performance "AF-S VR" version of the 70-300mm instead.... it's more expensive, but solves most of those shortcomings.
There's nothing to be gained and maybe even some further setbacks with the "AF-S VR" 18-55mm Nikkor, so I'd accept the AF-P if I wanted that lens.
The AF-S 18-140mm VR also solves most of the above shortcomings, but reportedly isn't as fast focusing as the AF-S 70-300mm VR.
Note that after factoring in the DX format sensor used in the D7500, an 18-140mm "acts like" 24-210mm would have on you AE-1.... In other words, this single lens actually covers greater range of focal lengths than most film camera user ever owned in their lifetime! The 18-55mm "acts like" a 24-83mm and the 70-300mm "acts like" a 105-450mm would on the film cameras.
Costco only offers the D7500 in kit with the two AF-P lenses. There are more and IMO better choices at other sellers...
B&H Photo and Adorama in NY bundles the D7500 with Nikkor AF-S 18-140mm VR DX lens for $1547 (free shipping and no sales tax most places outside NY).
Maybe you'll want to shoot scenic landscapes and will want to purchase the new, $306 Nikkor AF-P 10-20mm VR DX separately.
Later, if you want to shoot wildlife or sports, add a Nikkor AF-S 200-500mm f/5.6 VR DX for $1397.
Or, if you prefer a more compact yet powerful telephoto zoom, maybe the new Sigma 100-400mm for $800.
Or, perhaps you'll enjoy shooting macro and will want a lens to do that. Or maybe portraits or low light, and one or two large aperture primes such as 50mm f/1.4 would be ideal.
No need to "do it all" in a single purchase. In fact, it might be best to start with just the D7500 and the 18-140mm lens... then gradually add lenses in the future, if and when needs arise.
Just a thought, you also might want to consider the somewhat lower cost D7200... With 24MP it actually has higher resolution sensor than D7500 (21MP). But the trade-off is that it has a slower 6 frames per second continuous shooting rate (D7500 can do 8 fps). See a more detailed comparison here:
http://cameradecision.com/compare/Nikon-D7500-vs-Nikon-D7200 and Google for reviews of each camera. At about $250 less with the same AF-S 18-140mm VR lens, the D7200 might leave some funds for an additional lens or accessory you want right away, such as a flash or a tripod. I often think people spend too much on the camera and then short-change themselves on the lenses to use with it... as well as other essential accessories.
I'm just not a fan of letting Costco pick my gear... I prefer to pick things for myself.
I agree with some other responses that suggest you go to a store and handle various brands and models of cameras. Try to use the menus and even take a few shots, if the store will let you. While you can undoubtedly learn to use any of them well.... one or another just might seem easier.
You should also be prepared to spend some additional for other things that may or may not be included. For example, you'll need memory cards and maybe a spare battery. Lenses may or may not come with a matching lens hood, which i recommend always using because they help protect the lens from bumps. You also may need software, computer upgrades (RAM and HD storage space... possibly a graphics accelerator card). If you plan to do much printing... in addition to a photo quality printer, you might want to consider calibrating your computer monitor. A calibration device basically pays for itself over time, in savings of wasted ink and paper. And there are always other helpful accessories including tripods, flashes, and something to carry your kit in. I'd also highly recommend getting a guide book specific to whatever camera you buy, to help you get up to speed using it as quickly and painlessly as possible. Bryan Peterson's "Understanding Exposure" is also a very good read... an overview of how modern DSLRs work and tricks to get the best out of them. Even with your previous experience, you would probably find it valuable.
Have fun shopping!
