Recently I went to a couple of yardsales. I got 6 Cable Boxes with remotes (One Being a DVR) for $15. Two VCRs for $5 (5 for both) A crap load of CDs for $20. Ended up getting a broken 5-disc changer for free (I think its broken by the way it and the remote sounds, sounds like there's a cd flying around inside. Remote rattles when gently shook.) But I did find out that I made a good investment. Got an electric sander for $3 and threw it up on eBay. So far it's up to $12 with 4 days left to go, so I'll make some money on that.
