After reading all the comments on meer pipes and how they smoke cool, I started loooking on ebay to see what is available. I was suprised to find Kaywoodie made a block meerschaum. I have read some of the big names on this site, includig Altinok, SMS, Baki and another that seems to be associated with poor business relations. Here's the question? How do I tell what is a good meerschaum? Is it a matter of price? How are the old Kaywoodies?
