I bought the ubie for $10 and *love* it. The Ubie --Worlds smallest Vaporizer

As far as "how high" versus "amount smoked" the ubie allows me to smoke one third of the bud I would normally need to smoke in a joint. I love the thing. It also totally eliminated my smokers cough.

A downfall is that it probably heats the cannabis hotter then an expensive "volcano" type vaporizer... so you might get some smoke in there. But it still doesn't burn it if you use it right, so I don't know... maybe it is just as efficient. I've never used a volcano type vaporizer, so I can't compare the two. Also, the ubie is small, so you can't do but a few hits before you have to re-pack the chamber. For me its perfect though, because I don't smoke a ton.

The only other downfall of the ubie is that it is so short that, if I don't do the "fix" I'll describe in a second, then the hot air burns my throat like a short little one-hitter pipe. But to get around that, I use a second long glass pipe and just hold the ubie in the bowl end of that, essentially making the ubie like 5 times longer. It seals tight because of the rubber on the end of the ubie. Not only does that let the vapors cool significantly before I inhale them, but it lets me look at the ubie sideways as I vaporize so I can back off with the lighter once I start to see vapor coming down the tube. And I just empty and re-pack when all the bud has gone from green to dark brown.
