I started out just like you,I actually would think about my future greensmoke all day long,it made so much sense to me,I thought.Let me cut to the chase,don't get these bubblegum over the counter mall crap items(everything you listed)Do they suck beyond use?No,certainly not.Could they help you get into e cigs?Sure,when I was a gas station clerk we would have these lying around and I would often try them while my 510 was charging,theyre not that great.I would recommend a REGULAR ego for you.An EGO(Not an Ego-t) since you're just starting,is a 510 with a big ... battery basically for battery life beyond a 510's dream.Theyre gonna run a little more than regular 510's,but the reduced hassle of not needing a chafging case is well worth the extra $.I understand your initial interest in not wanting to deal with handling liquid,but would you buy a new car every time you need a tune up?Basically you're gonna easily spend 100-150 bucks getting off the ground with this life saving hobby,so why not vape the most cost effective way?(using your own liquid).Now the real question is whether or not you want a 3 piece(Batt,atty,cart)or a 2 piece(Battery,cartomizer)design.I just started getting into cartomizer(single piece that contains an atty and cart in one piece,but can also be refilled many times)after using the 3 piece for months and they both have advantages over the other.I could recommend grabbing the following in your first purchase-At least:2 ego batteries,2 or 3 regular atomizers(just remember an ego IS essentially a 510 in terms of what can go on it,so basically buy 510 stuff for your ego),a pack of 5 blank cartomizers(research filling methods for these,keywords being condom method to get you started[a pack of 5 cartomizers is about the price of one atomizer])at least 30 ml of e juice(I recommend 18 mg of nicotine).
Cant think of much else right now,but just remember that this investment will pay itself off in a few short months,just dont let yourself get caught up in the placebo effect of not seeing your nicotine device slowly burning down like a cig does.Some newbies feel the first few days of vaping as anti-climatic.Just remember that you're getting your nicotine fix in a more delicious,healthy way.
ENJOY!!
