Although its not an auction site & this may be the wrong forum I thought It was near enough.
A quick search shows this site had a quick mention in April 08 but I thought it could do with a mention again.

They have quite a few razors on, some at good prices
razor :: All Items on Ruby Lane
With it being in the US the postage is too much for me to buy single razors but there should be some bargains on for the US members.
