I have recently stirred a lot of interest in ecigs at work, and honestly I would never recommend a regular cig sized battery. I wasted the money starting out on a 510 kit. It was terrible, the prefilled carts were nasty, and the batteries would barely last a couple of hours. If only I would have asked questions before I bought I could have saved well over $100 getting started. If I was brand new coming in I would buy an eGo kit with blank 1.5 ohm or 2 ohm cartomizers, a couple of different eliquids from a well respected maker in flavors that actually sound like they might taste good, and a handful of spare cartos. Right now I own a SB, 3 18650 3000mah batteries, 2 AW IMR 18650 batteries, 2 eGo 900mah, 1 eGo 650mah (had it for almost 2 years), and 20 dual coil cartomizers, mostly 1.25 ohm, and a few 2 ohms. I also have about 200ml of really good tasting liquids, everything from coffee to lemonade cotton candy. I've just recently started using tanks too. I wouldn't necessarily recommend a tank to newbie, just because they can be a pain to get to work, and might turn some people off from ecigs if they were to get frustrated.
