Several laptops, open box iphone, rack-mount servers, high-speed scanners, hard drives, 2 9-track tape drives (yes really!), ...<p>You might run into an occasional problem, but sellers I've dealt with are mostly good about returns or exchanges if there is a problem.<p>I did buy some AMD CPU chips one time from a guy. I needed 12 to upgrade some servers but only bought 4 at first. Worked great. Then I ordered 20. I received a flat envelope in my mailbox. I thought "Hmm, that's odd, it looks empty." Instead of being smart and opening it while taking a video, I just opened it and -- it was empty. I figured it was just a shipping mistake, called the guy, and he said he shipped them (actually he had a shipping person doing the packing so they might have been the thief) and I was trying to rip him off. He ended up giving me a discount on the 12 I needed but didn't refund the 20 I didn't get. It was the only place I could get them, unfortunately.<p>The way I look at it, I've gotten pretty good deals on everything at eBay, so if I get a little screwed once in a while, it all averages out to be okay.
