You're not goign to find a product that is tuff enough to handle heavy smoking- not for very long- you might get hte odd atomizer that works liek a workhorse for more than a month, but really, most don't last that long from everyhtign I've read- some have beren known to last several months, but the ones I've read abotu aren't good vapor producers.
Probably the best advice is to buy from somewhere that has a great warrenty policy- 6 months or more- spend hte cash, and go with somethign like hte Janty KissBox classic, or even the 901 if you want a smaller design that is probably one of hte better ones on the market right now- but be aware, the 901 only lasts for a few cigg's worth of smoking before needing refilling
I'm currently smoking the Loongtotem mini cigg which produces a ton of vapor, but hte battery life is quite short- the Cartridges however last for quite a long time (some say for a couple of days, but I suspect hteir smoking habit might be lighter than mine as mine are lasting approx. 1 day, even with refilling, the heating coil burns the cloth and tastes terrible and I just chuck the cartridge at htat point rather than risking inhaling further burnt cloth smoke) But, I must state the throat hit on these is very very light unless you take double or even triple draws when inhaling- then you can get a fairly good throat hit, but oyu risk drying out the core sooner that way as I've foudn out- but, note hte cartridges do last all day long quite nicely. The loong has it's strengths and weaknesses- if you want ot read abotu them check out my thread as I've been givign my objective view of hte experience.
But hte standard eciggs that most people are using are the 901 and hte Janty- the 901 qould be probably hte best design to get your feet wet with as it's fairly innexpensive ($49 for hte kit at Cashme's 'puresmoker' site whichyou can find by clicking on his name or looking at his sig in his posts- tha atomzers btw are only $9.95 to replace- certainly cheap enough from his site-
You batteries hsould last you a month, perhaps more- but be aware, they are not all goign to as soem just don't work as well as others- that's the nature of hte beast I'm afraid- you'll also need soem backups incase of accidents as dropping them which will happen from time to time, will cause them to die prematurely.
A good recommendation is to have 3 batteries of each design ecigg, and two chargers, and a coupel of spare atomizers on hand- it's a bit expensive to get set up at first, but will save money in the logn run- also if you go with hte 901 model, be sure to buy soem esmokin juice to refill the cartridges with
