Advice vaporizer?, Please

I would like to try a vaporizer. Can anyone help with how they are used and whats the best kind.
Any suggestions ?

I wanna try that cheap Ubie one or whatever its called. I've done it through a light bulb before but my buddy was horrible at doing it and turned the bud black and charred.

From what i know the vape works by heating your budz instead of burning them..think like an oven...it heats up enough to vaporize the thc or good stuff in the buds..into a smooth vapor that you inhale. your left with dried useless bud and you dont actually burn the bud which is less smoke and burned plant matter entering your lungs..anyone feel free to correct me if im wrong...

with that being said i have had the please of takin a hit from a volcano and it was very nice but i cant affor a 500 doller vape.
