I've been happily bidding and winning on QuiBids for 18 months now. To any of the new people, take the time to read Q101 or visit their Facebook page if you have questions. Lots of people are happy to help!
Tip for consumers: Make sure to read Q101 and WATCH some auctions before you bid. Also, if you are using real bids, make sure you use the buy it now option if you don't win the auction, that way you don't lose your money.
