I'm going to praise The Machine once more. And if you combine it with the torch lighter it surely will become your best friend.

Huge advantage over GVG is that you can build it in 5 minutes and will cost you ten times cheaper.

You can smoke absolutely anything with it.

From my experience torch lighter plays important role and improves the usage experience quite a bit. It worms up the scrubber/metal mesh very fast and vapes the spice in a split second, you can inhale all of it in a hit or two, if your lungs can take it, of course.
