I am spending all my spare cash on that website. I have gotten some fantastic equipment through it, although to be frank some items I have bought bark at me. But I did get a 50mm f1.4 Nikkor. I love it. It was offered with a Nikon n70 body (a 1960s lens and a 1990s body) and I think that's why I got it for $20 and postage. Some really good stuff sells for way too much money so one has to be careful. rthomas is right. Why anyone would give a Hassey or a Leica M3 with Leitz lens away blows what I have left of my mind.
I have bought a couple items from the local Goodwill store through eBay. Back in '08, bought a chrome Nikomat FTn for $25+tax, and, recently picked up a 300/4.5 EDIF AIS Nikkor for $53+tax.
