I have been hooked since I used my friends extreme tower. I am all about diy as long as you can create something to the same degree in quality on the cheap. I actually got a digital hot temp cooking thermometer that goes up to like 600 degrees that I am going to borrow from work for a day to set one up.

As long as the heating element in the gun is ceramic and your using either glass or stainless steel connectors you should be good for the most part. I heard brass was fine because the temp isn't that hot, but I have always thought of brass as a no no so I wouldn't recommend it. You also need to know what temperature your weed is at, that is why a high temp thermometer is a necessity.

They sell turkey sized oven bags on the cheap as well. I like the convection / whip setups with soldering irons, but I want to go all the way. Anyone else have any good or better information?
