Ebay has a very nice search engine and the "favorites" feature which will e-mail you alerts when an item of interest comes up. People that want to find specific knife making equipment on ebay don't need spotting help here.
If you see an auction and you have a question about the item or want to discuss it, that's fine; start the thread and post the link... but be sure that you're not the seller or shilling for the seller, and that you start the discussion, tell why you thought that this one item out of all the items on eBay was particularly interesting. "i know the builder, its a good one," doesn't really pass muster as telling why you think this item is particularly interesting or starting a discussion.
