I don't know if you read high times at all, but in the January 2009 mag they have like 3 pages devoted to vapes, what ones are good and what ones are not. Its worth the read and its probably still on most shelves at your mag store.

Ones to AVOID are; Vapir One, IVape, Vapir Oxygen 2.0, and Mt. Fuji. They were both around 150, but they both gave off toxic smells. Mt Fuji was like 400 and a really tied to be like a volcano vape but failed.
The GOOD ones were Aromed($439), Easy Vape (vaporizergiant.com $149), Happy Vappy (happyvappy.com $ 219), the volcano ($669 rofl), and the Herbal aire (vaporizergiant.com $250)

I hope this helps, if i learned anything from doing some research on this it is that you get what you pay for, so don't cheap out. Your lungs will thank you. Go pick up that mag
