Trust me. It gets better. Very overwhelming and loaded with so many different options that it's hard to decide. The best thing you can do is skip the part where you buy things you don't like and just get to what you would end up buying in the end. The only problem is everyone here will tell you what you should or shouldn't buy. But, how do you know it's right for you? I've seen several ppl in the forum just straight up suggest buying an eGo or a Riva. And I always blew it off, like why are they pushing their opinions on me? I started with Vapor4Life. They really do dumb it down for you to be so simple. There is the occasional cleaning the end of the battery with rubbing alcohol and a q-tip. And sometimes, you have to pull the battery post up with a paper clip. They have videos on their site giving you how-to's in some of these areas.
But, you know what? I grew tired of my Vapor4Life stuff and just ordered an eGo this weekend. I'm kicking myself because I've spent probably close to $200 in about 2 months stocking up because I was so sure I would stick with V4L and it's almost a waste... Almost, I can still use the juice I bought and I have an adapter so I can use the cartos I bought on my new eGos. In the end, like everyone else has stated, it's going to be a trial and error process.
But if you want a straight up opinion, order an eGo (I would say order a Riva, but they typically don't come with pre-filled cartridges) The eGo kit is 39.99 at Liberty-Flights.com (click on the 20% off button in top left corner) and comes with everything you need from the start. Maybe consider ordering more cartridges and possibly some of the e-juice to continue use on the cartridges you get just to keep things going. But, if you have to fill the cartridges and feel you can become comfortable with this, then get the Riva. The only reason I didn't is because they were out of the Stainless with the chrome band... Gold is not my color
