Gixen has never let me down in placing bids on eBay. I've also used their ability to group items so that if I won an auction for one item, it would cancel the bids for the other auctions. It's totally free, but I paid for the deluxe service just to compensate them for the great service they've provided for me. I've only used 337 characters because I can't think of enough great things to say about it. I guess I don't have enough imagination. It's simple to use and works great. I highly recommend it!
