I asked in a 'vaping forum' what this guy (who has been on e-cigs for over 3+ years), would suggest what kind of kit would be good for someone who is wanting to start and is not sure what to buy, here's his reply...
I'm probably going to tell them what they don't want to hear - that anything that looks like a fag is pretty poor idea for two main reasons:
1 - it looks like a fag - that's more then likely to cause you all kinds of bother in public places where smoking is banned, because, bless 'em, the powers that be really can't tell the difference - if they've even heard of e-cigs - between a looky-likey and a proper fag.
2 - it's more than likely not going to do the job you're looking for it to do if you smoke more than around ten shop-bought fags a day - the battery won't be up to it, and you'll be frustrated by poor performance
I'd steer them in the direction of perhaps a Ritchy Era, or an Imist or a Neo - something along those lines - the Era if they're hell bent on slim dimensions, but either of the other two if they're open to it. A couple of months ago, before either of them came out, I'd have said an eGo-T or C style, and either of them would be a good starting point, too.
So for anyone here looking, who is maybe thinking of going the e-cig route, the kits suggested by him are very good and have been given great reviews.
