Well, even if I don't find anything for the price I'm looking to pay I'm willing to at least try. I picked up my 500, an A520 modulator, an A-Max emulator unit, and a bunch of software for $25 from a guy on Craigslist. So I've already been successful with Craigslist, and you can bet that I will continue to try and find better prices, where ever I can.
You can actually get some deals on CL! I got a A1200 setup loaded with BliZZard 1230 IV card, external Floppy, monitor etc for $20! Also got a Free A2000, and $10 A500. My recent deal was a FREE A4000 desktop!
But if you are not patient and can't wait 2-5 years for deals like the above, ebay is your friend.
Also you state you don't want or need a 2GB HD. Fine. Would you rather pay $50+ for a 500MB HD or $10 for a 2GB HD?

I installed a 1GB SCSI HD in my A590 and it runs great. I got the huge 1GB HD for FREE.
I think you were failing to see the obvious points that people were trying to make.
