I also started off on a mini "real cigarette" style ecig, unaware of the huge world of PVs and mods out there! After a couple of weeks I moved onto a vision eGo kit from Liberty Flights and it completely revolutionised my vaping experience! I was a bit concerned about using something that looks so different to a real cig in public, but I actually get less comments than I did before (probably because it didn't have a silly blue light on the end!). I now own a lavatube (which is about 5" long and 1" wide!!) although I still keep my eGo for when I am in a busy public place so as not to look too conspicuous. The list that Chrissie linked too is great, and I would definitely recommend an eGo kit to anyone who has been using a real cig style ecig. The only thing I would suggest is do a bit of research into the different between cartomisers, tank atomisers, cartridges and so on, this is what I found the most confusing...
