Actually, all I can seem to find are A1000s, at least on my local Craigslist. There are almost always more than two listings for NTSC A1000s in my area, and nothing else. Also, every person I know with an old Amiga has an A1000. It's almost like it was the most popular Amiga in my town.
I'd like to get my hands on an A500, but I can't find anybody local with one.
