Believe or not the $20 ubie (made by american smokeless) is a really effective vaporizer. It conserves like crazy and provides very strong effects (usually). The only downside is I've broken 3 (it was my fault each time though, but you still gotta handle them with care) and that when you burn the herbs (which has only happened to me once in over a year of use) the smoke is so close to your mouth that it burns your throat like crazy. I was considering buying a "real" vaporizer after I broke my first ubie, but ended up buying a few more instead for cheaper than one "real" vape and I'm happy with my investment so far. And it's also a convection vape which is good, the hot air from the lighter passes through the herbs rather than holding th lighter under the glass until it heats up the herbs which could take a long time.
