There are those who're classic purists. On any system other than a 68K based Amiga you are running an emulator to run classic software. Morphos,AROS, OS 4.1 all use UAE to run classic software. Minimig comes closest in that it's emulating the custom chips in firmware.
As a previous poster said, there's still a fair number of classic Amigas that find their way into op shops and markets that you can pick up for almost nothing. Ebay on a good day will get you a functional system at a somewhat reasonable price, but on a bad day will generate some astronomical prices. EBay is generally a seller's market.
You might also want to place an ad looking for Amigas in Craigslist. I know people who've gotten most any model that way, often for little more than the price of the petrol to pick it up.
