Vaporizers in the market

What are the types of vaporizers out there? I read somewhere that vaporizers slightly differ from one another, so what is it to be? Can someone explain the different types of vaporizers and which one they use?

 

I recently just bought a 50$ vaporizer, it works great but the expensive ones are where it gets great. The 50$ one is a hassle and gets really hot at the glass bulb and you have to watch out not to burn yourself etc, also the high you get varies on your temperature. But when you buy like a 300$ + vaporizer, you get one that's legit, and fills up like a bag with smoke. You then inhale this smoke whenever u want as the bag is sealed and only lets smoke in through 1 way. Its much better than the normal crappy vaporizer and i do hope you invest in it, it is definitively worth it.
