js, the finish on those Mastro's is called rusticated, they will smoke nice and cool in most cases. I also would stay away from ebay until you do a lot of home work. There are just too many things to look at and you will be overwhelmed. bigvan made some great suggestions also, you cannot go wrong with any of his if you see something you like. Here is another pipe that I believe will be a fantastic smoker.

Adam, a lot of new smokers have no idea what to even look at on ebay, how are they to know what is a quality pipe? You cannot expect a newbie to understand that a Jensen that might look nice is really a piece of crap. Also restoring isn't for everyone, I would never restore a pipe, I only buy pristine pipes on ebay. It takes months to understand the hundreds of different brands and what prices should be. I think that newbies who go to ebay unarmed get burned way more than they ever get a good deal. You were much different when you started, not everyone has the talent to refurbish like you.
