I had a very bad experience with uBid a couple months ago. I ordered a Sennheiser 580 and DSP Pro from them. First of all, it took three weeks for the package to get to me, and when I opened it I found not a set of headphones and a dsp processor, but a mouse!!! Not even a good mouse! The thing with uBid is that you have to wait about an hour on hold to talk to an actual person. They have this email form for asking questions but they never sent me any useful replies. They were all along the line of "we're looking into your problem." I eventually got it sorted out over the phone and received the correct package, but this took another 1-2 weeks. I have ordered things from them before and they arrived without incident, but they took a while to get to me. I don't think I'll buy anything from them again.
