Anyone ever tried Mazama Mugs? (made in Oregon, US).

Saw one on the shelf at a local coffee shop for $42! Had to pick it up and see what the fuss was about. I'm embarrassed to confess but I've never wanted a piece of crockery so bad! http://shopmazama.com/collections/coffee

I didn't give in, but wow, are they beautifully made (and heavy).
