what do you guys think of ubid.com, cuz i've been lookin there for a while, and i'm a little suspicious of why their products are soooooo cheap, i know some are used and refurbished, but even the new things are so dang cheap...how? Like you could get a good jvc or pioneer receiver/hometheater system with 5 spks and 1 sub for like 300 or 400, and it's good! how do they do this, would ne one care to give me advice or their opinion on ordering from ubid.com, thanx in advance!
