Hiya! If you think you want to try a KR808 style ecig, try Smokeless Image's Volt. Great battery, and it's the one that finally got me to stop. I have other batteries, but the Volt is go-to. For a basic kit, I'd recommend any kit for the battery of your choice that has TWO batteries and a charger plus some carts to start. PCC's are almost a must, though, for on the go, so stepping to the first size kit that offers a PCC is also a good idea.
I'm not affiliated with SI, but I am a loyal customer, not only because their products are so great but because they also have a customer service that is second to none! I recommend the $65 kit for a great starter kit (and the Mega PCC instead of the slider). Get sample packs of carts (they have 3 different ones) to try. A big tobacco flavor favorite is 555. Here is a coupon code that currently works for SI, and will give you a 16% (sixteen percent) discount on your order if you decide to try them: VoltSave
