Oh yeah here is a picture of my retro computer queen.

That is one VERY nice and clean looking Amiga

Personally i would say that for most people, a perfect Amiga would be as most people in this thread are saying is an A1200 with a fastram card with RTC (Say 4 or 8mb) and an internal IDE harddisk. Also a PCMCIA Compact Flash reader is very usefull.
With that setup you can have a really nice WB3.1 setup with WHDLOAD to run all your classic games from harddrive.
The A500/+ is a great machince and very capable and will also run most games through WHDload if you have a harddisk and at least 3mb of ram but it does lack the AGA and is more expensive to upgrade.
