I'm in the same boat as Pottz.
Bought one from Rockler, heat with a propane torch and brand. Just simple text or a standard design.

You can get fancier with self heated units but unless you are doing a bunch of stuff in series, not really worth the extra cost over the torch heated unit IMO.

As of the last few years I have been using my laser. Infinite design possibilities. Dr. John lases round wood "pucks" that he then attaches to projects, look very slick!
