Freebase DMT is soluable in NPS (non polar solvents).  Bestine is a non polar solvent.

I've never distilled my bestine (heptane), and don't feel that I need to.  It dries very clean.  I would use heptane over diethyl ether any day.  I think it evaporates too quickly to be a good recrystalization solvent, but then again I've never tried it.

As you said, don't try to distill it.

Naphtha will also work well to recrystalize, there is no need to try and make a binary solvent unless you are experimenting on new and better ways to recrystalize.  If it's your first time just stick with bestine or naphtha.
