Ok, I have a BluCig and not liking it too much. Battery life is horrible and there is not that much vapor. I smoked 1pad of Marlboro Ultra Lights before. I can't decide between the KR808D-1, the 510 or the eGo. The KR808 is just sexy and I hear it has a little more vapor and battery life than what I have. The only thing is it has cartos and I think I want attys. I'm not really sure of what I want but I think attys are more versatile. The 510 have a lot of vapor but the battery life isn't that great. I could get the 510 then add the eGo battery later right? Or should I go straight to the eGo? Urg, so confused! If I had the money I would just buy all three!
