David used to see his pipes at a Tinderbox here in Ohio. I had 8-9 or at one point, all good smokers. The construction was generally very good. I ended up trading most of them off because I went to smaller pipes, his are generally larger pieces. I think he gave up full time pipe making to devote more time to his band? Anyway, he is selling direct via eBay these days, not sure of any shops that carry his work. If you like bigger pipes, you will not be disappointed.
