Hi Pete,
Check out:
http://www.esnipe.com
I've used it on eBay for a couple of years.
It's free to new users for the first 14 days.
After that they charge you 25 cents for items up to $24.99 and then 1% of the price of the item up to $1,000.00 value with a maximum charge of $10.00.
You enter the item number, the maximum amount you want to pay and approx. 4 seconds before the auction ends Esnipe places your bid.
If you dont win it doesn't cost you a dime.

Take care,
Mike
