This has got to be one of the most frequently asked questions on this board.

Oh well, here goes again...

The volcano is supposed to be the best out there. I haven't tried it but everyone who has says they are the best. $550 is a lot to spend on a vap, however, when you consider how much weed you could get for that mush $. You can get a good vap for $150-$200. I have a Vapor Brothers which set me back about $150 and which works great. Stay away from the type like the BC VAP that have the glass dome. They don't work very well.
