Cabelas Canada is carrying a commercially manufactured, portable "smokeless" firepit that looks like it's built on the principles of a rocket stove. Since I have infinite wood to burn, I'm intrigued by the possibilities.

The manufacturer's website is here:

What do you think? It's kinda spendy at $299 CAD. Worth the money?
