Invision: I like the vaporwarez. A friend of mine has one and it is a good unit. It sounds like deftdrummer has a good idea of what he is talking about if you ask me.

Vapolution is what I own and like if it were my own kid - I am biased. I love this unit the mostest out of the 5 I've tried. The taste is best...hands down. The taste beats that of the 500$ volcano and the vaporwarez. And I know this!
You won't be disappointed in this unit and the boys in Chico, CA service beats any other company out there - you'll have your unit on doorstep in three days (shipping included). And I know this.
