The Vapir has had a bad past. I would recommend the Vapolution from Northern California herbal vaporizers- Vapolution Vaporizer. I just got one (off of a recommendation from someone here) and love it! I couldnt be more happy. It is under $150 shipped. It comes with an adaptor for your car, and you can even get a battery pack for it that lasts 2 hours.

Its the first all glass-on-glass vaporizer. It doesnt even have a metal screen. The taste is amazing, and the high is incredible. Trust me, you wont be dissapointed.
