The Pax Vaporizer by Ploom, my new favorite toy. Perfect for travel, discreet enough to sneak into concerts, parks and the like, and a great excuse to have a girl come to back my place at the end of the night.
A little pricey at $250 (last time I checked), but worth every penny. Especially when you consider:
1) How much a vape saves you on material (because you're not burning most of it off in the smoking process). This fact alone essentially pays for the vape given enough use, regardless of which model you go with, as you'll end up using half the herb you'd normally need.
2) The health benefits of not inhaling combustibles and carcinogens. Exactly what you end up inhaling depends, on course, on what you're putting in the bowl, but generally you'll get just that active ingredient along with some water vapor. Waaaaaaay better than tar and smoke particles.
3) How much fun it is to use. This thing is like the iPhone of vaporizers. It always gets oohs and ahs, even with stoner girls who have tried vapes before. There's no buttons or knobs, you just turn it on by popping open the mouthpiece, then pushing it back down when you're finished. The one light on the front changes color depending on whether it's heating, ready to go, charged, dying, etc.
It's especially handy when you're trying to be discreet. While the vapor will certainly retain a distinct odor, it won't stick to your face/hands/clothes like smoke will. And if you exhale into a sploof (an empty toilet paper roll stuffed with dryer sheets) there's absolutely no scent at all.
