If youre using some form of UAE then you'll really need something resembling a new system for it to give a reasonable result. A low end system these days can be picked up for about $200-$250 though, so its not too bad (granted these will have onboard gfx or very low spec gfx pcie card, but unless you want to play modern pc games then this wont be an issue). For that you'll get a cheap dual core system, 80-160 gig hdd space and 1 gig ram, which is enough for UAE use. Reason I mention this is 'cos you said something about $100 old pcs. Definately worth spending the extra if you have it. Another option if you can get your hands on it is amithlon. Runs a lot quicker than UAE, and a 1ghz pc will be enough to give good results. Also boots your pc straight into Amiga OS3.9, so you dont need to boot another OS to launch your emulator. Makes a better option than UAE for Amiga music software as well. Bare in mind though that with that option you get next to no custom chipset emulation, although this is only really an issue if old games and/or scene demos are your thing. Hope this info. is of some use.
