I've had nothing but good experiences with SwipeBids. I'd tried BidCactus before but it was getting to be too complicated. SwipeBids is much easier to use. It's true you have to pay $150 up front which seems like a lot, but for the experience it was worth it for me. Once I had won a bunch of bid packs I was able to deal with the bigger auctions fairly well. Obviously you have to pay attention to the bidding process but once you get the hang of it, it's a lot of fun. I know I've saved more money overall then I've paid for my bids, so I'm happy.
