Do yourself a favor and read some more, but not marketing stuff. Read all the appeals for help from noobs who bought an eGo-T. Read what most people do after they've had their eGo-T for a while. They ditch the "T" part and stick clearomizers or cartomizers on them. The eGo-T is nothing like dripping. It's finicky, leaky and usually tastes like burnt plastic.
Stick with the Volt. It's better than an eGo-T and is the best cig-like PV on the market. Get automatic batteries if you must. By the time they wear out, you'll be looking for manual batteries. There is a good reason why no high-end e-cig uses an automatic battery. No big battery APV uses an automatic battery. Even eGos don't use automatic batteries. Can you think of why that might be?
I don't know... because they don't want a hands-free experience?
