Here's what I do:

1. Contact the seller immediately and ask whether there are any defects that may not have shown up in the photo or in the item description. It gives the seller a chance to really evaluate the items again. This may mean gently running a thumbnail along the edge to check for tiny nicks. Some sellers may not be comfortable doing this. A toothpick can be a nice little probe in that case.

2. If you're not happy with the photo in the auction, ask for close-up shots. Indicate specifically which areas of the razor you'd like to see. I'd think twice about bidding on any item, whether it's a steal or not, if the seller won't at least try to send me some better photos.

3. Ask about returns, and mention that you're a collector who enjoys using the razors and that you really don't want a razor with a substantial defect. Will the seller refund your payment in full if you find a defect in the item? If so, great. If not, go with your gut instinct.

4. If you win the item, inspect it carefully the moment it arrives. If you find a defect that was not clearly photographed or described in the auction, take some photos and e-mail them to the seller with an explanation. Hopefully, a return scenario will have been ironed out with the seller before the razor arrives.

5. Make sure all communications are handled through the eBay system.
