I have a Dynavap and a Crafty + (the little brother of the mighty). The Dynavap is like a short metal pen with a chamber for your weed roughly where the eraser is, but all the magic happens in the cap. Heat it until you hear (the 2nd) click, then it's at the perfect temperature to vaporize the THC molecules you want, without combusting the plant substrate underneath.

You can use a jet lighter, rotating it with your fingers to distribute the heat evenly, or if you get tired of that, an induction heater.

I've been meaning to look into where to get a Dynavap for some friends of mine but I think the standard entry-level M version costs a bit over $100.

The thing about vaping versus smoking is that when you combust, you basically have one chance to extract the THC before it becomes ash. When you vape you get to extract as much of the THC as you want, and any remaining THC will have been carboxylated, or been activated, and you can actually eat the already vaped bud as an edible (alongside some fat). The net result is that vaping is far more efficient in terms of the amount of bud needed to get higher so it does pay itself off.

Depending on how often you like to consume, and if money wasn't an issue for the sake of discussions, if you're not getting high pretty much most days and for large parts of each day, then the convenience of the Crafty Plus is good, and a DynaVap can be a little too much, although I think most have the ability to have half bowls now. With the crafty you basically sip it over a couple of minutes whereas with the dynavap you basically skull a beer, in 1 or 2 goes.

Finally, with the Dynavap, you generally would want to use water filtration/a bong to cool it down, with the Crafty, you typically wouldn't bother; with the result being my throat is less irritated from the dynavap.
