I use BidNapper but here are many others. Their servers are continually pinging eBay and measuring the latency. There is no way a human can beat them for last (nano)second timing. Plus, you don't need to sit there with your finger on the mouse.

Bidding the normal way just telegraphs interest and invites attention and competition. Decide what you are willing to pay, activate the Bidnapper (or whatever) and wait for the email to tell you whether you won or not.
