a vaporizer is worth every penny that you spend on it. do NOT buy a cheap vap, that's the best advice i have. as you'll hear and read from many different sources, a volcano is simply the best way to go. many people complain about the price and don't consider that you can buy them used, same great quality at alot of times half the price:

get the solid state if possible especially if you don't mind cleaning once in a while as the easy valve gets expensive with constantly buying replacement heads.

think of the money you'll spend as an investment, the heavier smoker you are the faster you'll return the money you spent. good luck.
