While I do like my MVP, I wouldn't necessarily recommend it to a beginner. It's big and heavy, not something you would want to take to work or out in public. Have you tried a disposable? They aren't the greatest, but they are a good, cheap way to see if vaping might be something you might like. From there, I would recommend an eGo. The variable voltage ones are about $10 more than the regular ones, so that aspect is up to you. However, I feel like an eGo would not be a waste of money either way. They are a good backup and very concealable. I still take mine to work, despite having moved up in the vaping world. They look like cigs and you won't get many puzzled questions from other people. I'm not one of the people that is huge into variable voltage, so the whole Spinner/Twist thing doesn't really tickle my fancy. I set my stuff and forget about it, unless the juice tastes bad. That is the only time I reset my voltage.
Second, whatever you get to top your eGo is disposable. So get a few different clearomizers and tanks to see what you like best. Each have their own strengths, so when you have to replace them, you will know what kind to buy. Anyways, no matter what you get, the atomizers will only last 3-4 weeks depending on use. After that you have to either replace the heads or buy new stuff. I used to love Kanger MT3's, but now I am more into Vivi Novas and tanks. Things change as you get more into vaping.
