Two good places to check: GotVape.com and VaporWarehouse.com.
I got my handsfree vapor bros. from vaporwarehouse and I recommend it.

The vapor king (from gotvape) looks like a very good model with the same design and my vapor bros, and $40 less. You can find one on ebay for ~$110 (w/ free ship and free grinder) from the same GotVape store where it retails for $150.
In my opinion, any handsfree box-and-whip style is your best bang for buck. Mine is already two years old and to me, it's my best buy.

If you have a bong (like I do), you can also buy an adapter that attachs your whip to your bong for a vaporbong. This is one benefit over the volcano. Another is some units have an advertised 30 second warm up time. You also use less herb than traditional methods.

Another bonus is the "duff" or leftovers of herb which you can use to cook, make hash oil, or smoke/re-vape a second time (although not preferred).
