Yeah. The difference is that they are convection vaporizers. The BC vape has a little hotplate that singes your herbs (this is called 'conduction vaporization').. while the box-style models have a heating element that passes air through the herbs (this is 'convection vaporization').

You can find a good Vapor Cannon with a 5 year warranty and a ceramic heating for around $120 on ebay.com

Definately worth the extra cash spent.. you will be pleased.
