Some very good recommendations so far. I'll add Halloran's double glass to that list as well, I like it better than my Crystal Mistress, which is saying a lot because the Mistress is a killer. Some other options to add, Andy Kaiser makes a great ceramic pot, I have an order in for a Lon Trice tumbled aluminum, which is similar to Dawkins stoned aluminum, and it sounds fantastic. For slates, I've got a Leopardwood slate over glass from Ricky Padgett that sings and will be in my vest opening day. Lots of good choices out there, good luck in your search...
