LOL, I do a craigslist search for "Amiga" almost every day, and come up with nada. Like hen's teeth in the DC area! 
I'm in the DC area and struck gold twice. First time, browsing in a pawn shop, I saw an Amiga 2500 box, with no keyboard, mouse or cables. The owner did not know what it was or what to do with it. I traded him 3 obsoleted PC compatible computers which was given away from my office for it. That made more sense to him. Anyway, I brought the box home. Besides the A2630 accelerator, it had the Commodore Scan Doubler card and a 8088 Bridgeboard in it. Should have suspected it when I noticed it had a 5.25" floppy drive built in. The hard drive was small, only 52 MB. But the accelerator had 4 MB of RAM on it.
Second time, I saw an auction on EBay. The guy was selling his A500 kit for 1 cent (buy it now). He basically wanted to make space in his garage. So I bit. When I got there, I was glad I had a van. That A500 was loaded to the gills: GVP A530 (8 MB RAM, 120 MB HD), ScanDoubler, 2 MB Chip RAM, 1.3/2.1 ROM Switcher, boxes of software and parts. The parts included a second GVP A530 brand-new in box, a third GVP A530 parts only, a parts only A500, Commodore 1942 bi-sync monitor, a joystick, extra cables, extra 3.5" external drives, an extra scan-doubler, extra A500 keyboard and I still have not gone through all the boxes.
I did not have too much space myself, so I put an ad in craigslist and got rid of my Mac collection (mostly 680x0's and a couple early PowerPC's). Made some Mac-head real happy. But I was much happier with my expanded Amiga collection.
