I smoked on one of these before, they really are worth what you pay for them.
(if you dont mind me asking, how much did you pay?)
I have a ghetto vaporizer set up. It uses a bong, long 3 inch tubular bowl, and a heat gun (from any hardware store). You run the heat gun at about 300 degrees celcius so ensure you find one with adjustable temperature controls. Its kinda hard to explain with text, i should get some pics up here.
