This kit I got from my local B&M. It doesn't have the best drilling though. Smokes good regardless. But I'd say the best place to get one is from Mark Tinsky's website.

Just check out the pipe kit section. Also check out his pipes. He's great.
I use a variable speed dremel with the drum sander attachment to do the majority of the work. After that I sand with 100 grit then 220 grit and then 400 grit sandpapers until it's as smooth as it can be. Then I use a solid block of carnuba wax with the dremel and a buffing attachment. Gives it that nice gleem. This pipe is actually lighter than it looks. It does take a strong jaw to hang on to though. It's better to alternate holding it and letting it hang. As far as my Clearance is concerned C, what they don't know don't hurt me. Although they did just pretty much legalize it up in Denver...
