And here is another reference for you.http://www.ecigology.com/e-cig-glossary/
The best advice I can give you is to skip all the cig-a-likes and head straight for an itaste vv3. You will love it. It is nice in your hand and gives a decent vapor. I started with Green Smoke (cig-a-like, much like the V2) and after a week found that wasn't going to do it for me. Then I bought a Halo G6 with mini tanks (still looks like a cig, but the mini-tanks allow you to fill with whatever juice you'd like--I still use mine to sample juices). Then I got the vv3 and it was a whole new world of vaping. On the way to it, though, I spent well over $100, maybe even $200, for things I will never use. So in your shoes, I would start more or less at the itaste vv3 level (there are other choices similar to it, also). If you can go to a vape shop, that is where you likely will get a better idea of what works for you. Be warned that you may get a case of "shiny-itis) and keep buying stuff, but first you need to find the thing that you will enjoy using so much that you don't even think about buying a pack of cigs.
