Honestly? It really doesn't matter if you buy the Provari now or later-you will eventually. You've been bitten by the bug. I started with a regular eGo, went to the eGo twist, then jumped all in with the Provari less than 2 weeks ago. I'm still using all 3 devices for certain purposes, and am already thinking about my next mod. Every device has a purpose, and you always need backups. I can tell the Provari will be my workhorse, but what if it needs to go to the shop? I'm going to need another mod to take it's place, at least temporarily. Or then there's the fact that the box mods look interesting. Maybe I just want to add to my collection at some point.......I second (or third, or whatever) the idea that you should go with the twist first. It will allow you to see if VV is all that it's hyped to be. Some folks love it, some don't need it. Go from there, and whatever you decide, VAPE ON!
