So you've tried an e cig before and you like it? I'm new as well and lurked on this board for the better part of a week to make up my mind. For me money was a concern and didn't want to go all in until I knew for sure I liked it (and I do like it very much at this point).
The best bang for your buck is an eGo c twist battery. It's variable voltage (3.2v -4.8) with good battery life. Comes in 650, 900, 1000 mah varieties (larger number holds a charge longer, battery performs the same until it dies). It has limitations though in terms of choosing tanks, cartomizers etc.... that are low resistance and dual coil tanks or carts are probably not going to work stellar. This style of battery from Joyetech has many clones (some good , some bad). I see you're located in New York so myvaporstore.com is a genuine joyetech OEM partner , good prices, selection and I would assume super fast shipping for you. If you go this route make sure your chargers for the eGo have the MVS logo on them. Difference from 7-8 hour charge to 3.5 hour charge on a 1000 mah battery. They have good starter kits that come with an assortment of tanks and stuff. Even if you decide early on to go more advance having an eGo twist battery on hand is a staple for most vapors and a good go to battery in a pinch or if you find public vaping awkward. (note: The new kanger pro tank bottom coil using pyrex glass looks really nice, haven't purchased one yet, but will very soon....comes with additional two replacement heads).
Juice is subjective and is kind of hit and miss in the beginning.... what may taste like ... to you may be the finest tasting juice to somebody else.
There is NET (naturally extracted Tobacco) juice... WTA (whole tobacco alkaloid) ... etc.... some fruit flavors taste natural , others synthetic...blah blah blah
Now if you're an all in type of person and just want something super freaking fantastic from the start and money is of little concern I would look at getting a provari or a darwin. Good luck on finding a darwin though. darwin does all the thinking for you, but does not look like a traditional vape device and has it's drawbacks as well (mostly with tanks and the swivel arm going down, use adapter and slim tanks kinda gets by this flaw).
Probably said too much....very new, but the stuff people are doing is pretty incredible. There are tanks out there in the $200 and up price range alone. Using stainless steel mesh wicks, ceramic.... building your own coils, using cotton instead of silica wick... it's mind boggling for newcomers like us!!!!! lol..... Sorry if I've confused you even more.....if so grab an eGo twist to start, that's what I've been using the last few weeks and been happy with it. Get at least two batteries (that is what the starter kits are for). Watch some videos and read on cause I've really only touched on the subject and everyone will have their own opinion. Good luck.
