it all depends on yer finanicial situation, if uve got some spare cash, buy a good on, i spent £330 on the volcano vaporizer and it was worth it! to heat up the volc takes about 4-5 mins, if someone cant wait that long to get stonned, theyve got a problem! to breath vapor, you just do it the same as you would smoke, but the problem is vapor is very easy on the throat once yer use to it, coz at first it will iritate yer throat. so DONT inhale to much as they can get you very stonned. the volcano makes a slight humming noise when its switched on, and i surpose other vaporizers make some noise. vaporized skunk still gives off some smell, but its nothing compared to a bong or spliff. my advice - buy the best you can afford
