GarageBuy

GarageBuy is a free application for MacOSX where you can bid, search, and browse eBay with a lot more ease than eBay's interface.

What's really cool about GarageBuy is the thought out way of browsing and searching auctions. You can search anything, and save that search for future reference. You can bid directly from the client software as long as you allow it to interact with eBay (which you have to authorize). This is basically the little brother of GarageSale, which is the auction selling/merchant side of the software package that actually costs a little bit. But for the eBay buyer, GarageBuy is definitely worth your time for the quickness and ease to eBay satisfaction.
