IMO, vaporizors are well worth it, you can conserve your stash more, so eventually they will pay for themselves. It take less bud to achieve the same high as with burning. Also, the health benefits cannot be denied. All the plant matter you inhale with burning is not good for your lungs, especially when you are a heavy toker like me. You def. get what you pay for w/them. There are a lot of shitty ones on the market. Variable temp control is a must, as different buds vaporize at different temps. The high is cleaner and more mellow, and IMO more enjoyable. I think you get a better more pure taste from them as well. It's weird though because it smells like burnt popcorn. They will make you cough if you inhale too much, but I think you can inhale more THC "per capita" then with burning. You will know when it's done because your bud will be all dried out and it will turn a greenish brown color. It's like the soul was sucked out of it. You will know when it's done. I've never used a Vapzilla, so I don't know but it looks nice, The Volcano is the mack daddy of all. Any of the ones that vaporize into a bag are really nice. If your not looking to spend as much, the vaporbrothers vaporizer is a nice piece. IMO, it's the best bang for your buck out there, only $160-$180. They are a good company as well. They repaired mine when I dropped it and broke the heating element for $24 bucks----Peace
P.S. Nothing will beat a fatty blunt of some dank though!
