I've had great luck with fishing stuff:
Abu 5501 C3 AND Citica B (spare cranking reel) for $45, just some cleaning/lubing and they were perfect.
$200+ Quantum PT Swimbait rod for $50
2 Jointed Jitterbugs and a Sputterbuzz, all were black and older (higher quality) models, for $10
I bought a used roadbike off ebay though that was absolutely trashed, I went round and round with the seller and got nowhere. I was a pro-mechanic for a while so it was nothing I couldn't fix, it was just not advertised as needing 4 hours worth of work to make it ridable.
I have no problem with ebay as long as the seller has a good rep and if it's used I need to be able to handle any mechanical issues that may come with it. If I'm comfortable rebuilding a used reel/bike/etc. I'll bid.
