thanks again i have been looking into these Vapolution's and even called a bunch of head shops in my area. the word is that the majority of these get returned, and yes they have been getting better with each version but the shotty fan motor has no excuse nor can i have this thing humming loudly while iam filling up a bag, which needs to be replaced. all in all i think the best option for a convection vaporizer under 2 bills is the Vapureys. the glass top and the bulb are standard pieces available at most hardware stores. i will probably be ordering one tonight unless someone has a better idea
