^Never used a 500 did you?
I had an s900 some years back, and the 500 chops samples just like it did. I'd assume the mpc60, and mpc3000 also do chopping just like mpc500.
All of your favorite 90's hip hop was done this way. None of the old school samplers had visual wave editing until the mpc2000, and others from that time frame, 97ish.
You can "export" just like you did with samplers years ago by recording each track directly into a recording source.
Back then it was DAT recorders, and reel2reels. Soundcards/audio interfaces are what people use now.
The 500 is right in the league with the 2000 in terms of standalone features.
I can't really see it holding someone back.
No sampler can. Give me an old Roland ms-1, and I bet I could not do any better with a mpc5000.
You get more options with the high end models, but those options don't matter much anymore since any processing you could ever want being a few mouse clicks away in a daw.
You might ask, why not just use the cheapest sampler available then, and the answer is you probably could, and get by in a massive pro career using a $75 sampler, a cheap audio interface with freeware.
People just like to buy stuff.

To answer the question the 1000 has more features, pads, midi/audio ins/outs, etc.
$500ish should get you a used 1000.
Used 500's in the $300 range is common.
