Admittedly I'm new as well, but having just gone through what you are about to, here's my experience. I did drop a few hundred on testing out several models, so hopefully I can save you from that. Blu, V2, SafeCig and the KR808D-1 were what I tried.
I also wanted something similar in look and feel as an analog. Where I landed and what I now use is the KR808D-1. I was a pack / day smoker and the battery gets me through the work day and part of the evening having used it about a week now. I will admit I still have 5 or 6 analogs / day as I'm tapering off of them so I may need to swap batteries mid day at some point. Anticipating this, I ordered a personal charging case (PCC) which resembles the size and shape of a pack of cigarettes. If my battery dies, I have a back-up ready to go and don't need a wall socket or computer to charge. That solved the battery life issue which hasn't really been an issue to this point. The KR808D-1 has good, consistent vapor and really provides a throat hit similar to an analog. Only down side I can see is it is a bit noisier than the others I tried (my wife says it sounds like a .... without the bubbles).
With the others I tried here's a list of the issues: expensive, inconsistent (some draws are good others not), quality issues (mostly with the Blu), being locked into getting refills only through them (SafeCig mostly), V2 took a long time to process my order. My suggestion is grab a starter kit for the KR808D-1 and buy some pre-filled cartridges (the KR will come with empties you have to fill). I'm still mastering the art of filling my own and would not have wanted to mess with filling carts while I was finding the right device. Hope this helps!
