Ren, have you never tried one of the various bid-sniping programs for ebay?
You can just set up the maximum you are wanting to pay, increments to increase in with some of them afaik, time remaining to automatically put in the bid, and the exact moment you want your bid to go in, that uses the computer to put in the bid for you automatically, allowing you to jump in just a few seconds before the close of the auction and outbid the user as long as they haven't bid over the maximum price you preset as being willing to pay.
I've used them on close auctions before, and jumped in there 3 seconds before closing time and outbid the last bidder by a penny or two more than they bid, snatching the item away from under their noses so close to the finish of the auction they wouldn't even have time to click the refresh button, 'bid' and write in a new figure using the automatic sniper software. Its really useful, don't think I've ever lost an auction using software of that sort.
