This is what I use:
GAMES:
modded XBOX with UAEX (this get me an A1200 with 32 megs of ram with sys3 WB and all the bells and whistles)
Runs A500, A1200, CD32 games (cd32 games play off orignal CD's)
REAL AMIGA 1200: for games, this is my last Amiga rebuilding it from spare parts but this will live alongside the Wii, XBOX1, Xbox360, and ps3.
HIGH END:
MacBook dual core with Amigakit and a copy of my A4000t 060 Video Toaster Flyer original hard drive with setup dating back originally to 1993, I've continually updated this over the years. If I were to try and create an amiga this powerfull I'd pay $2000 or more based on current EBAY prices.
Emualtion kicks ass, but I have a serious case of retro additcion due to Mini-MIG. Was actually getting rid of my Amiga stuff when Mini-MIG came along, as I was trying to mass produce the thing I started to use a real Amiga vs. Minimig to check compatibility and show investors what the real machines were caplable of.
