Recently bought this. Even more recently received in the mail. It isn't explicitly for DMT, but I imagine if I do successfully vaporize DMT with it that it will become explicitly for DMT.
Stainless Steel Coil

I haven't used this yet for any purpose, but if you were going to vaporize freebase how would you use this tool? I am ignorant in these matters.

Well I have this vaporizer for smoking weed, and it's great for that, but I don't think it would be doable with DMT for many reasons. Let me try to give you some :
a) the coils are not soldered. If you bend the pipe, it opens up. With DMT that could be catastrophic.
b) the way you load it up also makes it totally impractical for spice. You have to open it, hold it vertically, load it up, close it and hold it horizontally in order to smoke.
c) it is totally opaque, so you can't see when the DMT turns into liquid then vapor, and regulating the heat is thus a matter of pure luck as you can't see the flame.

a) & b), you could find your way around by using a copper or steel mesh, but c) is the real show stopper...
