Just tried my vaporizor today, I am very impressed, very little smoke, easy on the throat and lungs and uses less herb. I payed $39.95US and that included a grinder.I have seen others that go for $159.99 up to $500. Not sure why the price range, I think it has to do with temp control and the heating element. Start with a cheap one and see if you like it ot not. One thing the herb does not tatse as good, I guess everything in life is a trade off.
