If you want a more cig like setup (doing mtl inhales or mouth to lung) get a nautilus
tank, i used the first gen one on my first month when i quitted the analogs, the big size of the first one makes it pretty easy to have an all day vape though the juices have to be closer to 50/50 or more pg. Imho the mod dosen't really matter when you start, i say start with something small enough that'll satisfy you battery size wise and a
tank (sub or above 0hm idk what you want mostly). I used an aspire evo 75 though plenty of functions and uses replacable batteries which is a big + since i can just carry a bunch of em and replace them whenever they run out of
juice 
(no puns intended here aha)
