Well, I started using the BC type vaporizers. Those are just Modified Soldering Iron - aka MSI - technology. I then looked into the box/whip types, but I didn't like them at all. I finally bit the bullet and got the Volcano, and I could not be more pleased. It's expensive but supposedly built to medical grade standards. Whatever, the thing works and works well. The Gotvape site is good, they have a few other "bag" vaporizers not as expensive. I think the bag type are best, but I can only vouch for the Volcano. Also - if you do decide to get it, another vape site sells it for the same price - vapeworld maybe - and they give you the $50 carrying case.
