The Amiga 1000 is a great machine. They can still be found for $300 - $400 working. You will have an easier time finding an A500, and they are more expandable. They are more powerful even though the numbering is lower, as they can easily access 1 MB of RAM, and the A1000 can only handle 512kb easily. (Of course expansions are available for both!)
I have managed to find five Amigas for reasonable prices in the past year. Never paid more than $350 for any of them, most well under $200.
I just picked up an Amiga 1000 last week at AmiWest and I am enjoying that. You can check with the guys at the S.A.C.C. Sacremento users group, as they often have Amiga's for sale.
Take a look at my YouTube Channel if you want to get excited again for the Amiga. I do a weekly series on Amiga hardware and software.
