Dude, I think the end of your search is near...ever hear of a Vapor Genie?

(i have the lighter colored one in the picture of the light & dark wood genies)

A little background: my boyfriend bought the HerbalAire vaporizer for himself and I last year. He's a vocalist and didn't want to deal with the stress of inhaling so many carcinogens via combustion. Anyway, the purchase came with a free Vapor Gene, a pocket vaporizer, and he gave it to me as a gift.

Let me tell you... that little fucker will set you on your ass. It takes some getting used to, and you need a steady hand to light it so you don't burn anything, but if used properly it can deliver quite a nice high. Total vaporization.

Seems to be what you're looking for as far as pipe-replacement goes. Good luck with your search.
