I buy them but not for scrap anymore. For me it's fun to see which ones I can repair myself. Others I will make into entirely different pieces of jewelry. I have then sold these individually on ebay and at local craft shows, and in large ebay lots of wearable or repairable or junk lots. I probably make very little money on them, but this is one of my main hobbies that I do just because I love it. Some lots are really nice, but there are always some bad ones, too. Years ago I was taken really bad by an ebayer - $1500 worth of total junk, and ebay at that time at least would not force him to take it back and refund my money. Since then I steer clear of buying just for supposed "gold" and "silver" and buy what I think I can personally rehab. Hopefully others have had better luck.
