I got a vaporizer a while back for recreational use and I have to say it is awesome. It is much more efficient, easier on the lungs, and you will certainly get really really high though it's a different kind of high. The thing about vaporizing is that you get the effects of the thc without burning the weed. So will you get stoned? Yes. But you don't get the full bouquet as you do with smoking it.

I don't know this for sure but it seems to me that there are more cannabinoids that create different highs and some of those you only get when the weed is actually burned.

Should you get a vaporizer? I say definitely, esp. if you want something easier on the lungs but don't think that you won't ever cough you can still take very big hits that will blow your mind but it won't be as harsh. I use mine frequently but I also continue to use my bong, roll blunts etc. The high you get from vaping is a really powerful head high.
