Well, looks like I'm ready to jump into the world of vaping...but wow, what a bunch of overwhelming information! I've managed to learn some things and confuse myself, all at the same time! 
First off, I've found the one I think I'd like to buy. Is First Vapor a reputable vendor? Anyone had experience with them? They have a snazzy hot pink number that I really dig...bigger battery, etc., seems priced about right. And it's hot pink. Did I mention that?
Secondly, about juices...is mixing your own advised, or is it just easier to get some premades to begin with? I don't really want to be doing too much fiddly stuff as I'm starting out and get overwhelmed. And I have NO idea how much to start off with. Will a few small sample bottles be enough to last me a couple of weeks (I currently smoke a pack a day)? I'm definitely on a budget and don't want to spend too much to start with, but I don't want to run out in three days and smoke analogs while I'm waiting for more juice.
Third, cartomizers replace an atomizer and cartridge, correct? Which option is cheaper overall in the long run?
I'm sure I'll have more questions as I go, but those are my main ones for now. Thanks!
