You mean other than the two models (from unknown manufacturers) that you currently sell on your Vapor Cig website? [Is the pink one a DSE901/RN4075 and the white one a DSE103/RN4081?]
The most popular model among ECF members is the Joye 510, but the eGO/Tornado (also using the 510 atty) is coming on strong. The Kr8 also has a large following. The 510 and Kr8 are the two models I recommend to new vapers and the first and second place winners in the Vapy Awards. [If the voting were to occur today, I think the eGO/Tornado might edge out one of those.]
There are many other good models in each size class. In fact my favorite is the penstyle (DSE801, RN4072, BE112, M201, and Joye302), but that is not nearly as popular as the 510 and Kr8 (and 901) and that new eGO/Tornado.
