ItsZe, welcome first off and Congrats on getting off the Cigs. As for a setup that would allow chain vaping there are many, but I will tell you what I have and use.
I have a VaporFlask Stout with a Kabuki Tank, second I also have a Vapor Shark DNA 40R(has Temp Control) with a Russian 91% running a 1.4 ohm coil. Both of these are part of my daily rotation and will allow for chain vaping. Although I rarely do that. Hope that helps. As earlier stated though there are many options out there.
Keep on Vaping
