Yeah, A500s can be picked up VERY cheaply! But in terms of playing the later games, an AGA chipset is nice, as is a 68030, hard drive and WHDLoad - and all of these are cheaper to add to a stock A1200 than a stock A500. Or just buy one of each!
As for that A3K - seems clean and a reasonable price. But again, no AGA for those machines, which may give a problem as AmigaFan's use would seem to be primarily for gaming.
