I'm only about 5 months into vaping but these companies (below) all offer the same cig lookalike type model (meaning a kr808 battery set up) and their cartomizers and batteries are mostly interchangeable:
Bloog
Smokeless Image (the volt)
Vapor 4 Life (vapor king)
Theres some others out there like Blu. I would go with one of the above and my personal recommendation is Vapor 4 Life. They have excellent customer service and the stuff is priced right. They also have frequent sales in the 20-30% off range. Like them on facebook and you can get access to that.
