I would go with the silver surfer or the da budda... They are made by the same company. 7th floor which is out of colorado springs. They are super nice, you can call them directly at 1-719-570-9928 or can go to their website Silver Surfer Herbal Vaporizer Oil Diffuser/ Ceramic heater. You can find them at most smoke shops, but its cheaper to go thru them.
