im not sure they are really vintage yet (they are still "old", vintage is close to 20+ years imo), at least the 1000 isnt. All mpcs have 16 levels. The differences are mainly in size, fx built in, floppy vs cf, sound very slightly different, 1000 has output board stock, pads may an issue on 1000, display may be an issue on xl. None of that stuff is make or break imo, its more of what works for you.
