had same prob once, and then other times not wanting to stay up all hours waiting for an auction to end, so i ended up biting the bullet and signing up with auctionsniper, best thing ever done with regards to ebay - give you a few free snipes so you can try it out and get the hang of it, then you have to add minimum $5 into an account so you pay when you win, 25c per win, not too bad when you think about it!.
I won a KG Panini Limited JSY/10 i was after yesterday so happy, set my max bid, 5 seconds lead time and got it. Sometimes it works and sometimes doesnt, but it lets you know if your max bid you are going to try to sniper for is below the current bid so you can decide from there.
