I think, as you are just trying to find what you like, at this stage, you should get one of the 5v box mods or maybe a VV cheapy. You can usually get good buys on Buzz, Infinity, Monkey box, Little Sister, Joker on classifieds for under $100. Will usually include aset of batteries too.
Dont get me wrong, I love my GLV, but it did take some getting used to first. Make sure if you decide to jump right in, that you get a stash of both batteries and cartos. Nothing sucks more than getting that PV you've been waiting for, only to find out you cant use it til the rest of the stuff you need arrives. You'll prolly want standard or HR cartos, maybe 2.6oAm or higher...
