Hello and welcome to ecf.
I, too, was a very heavy smoker for many years. I found that the eGos just were not powerful enough to keep me off cigs for long. Now they have so many new and improved devices that you should be able to find a pv that is powerful enough to get the job done without costing the bank. Look at the MPV2. A good clearomizer like the protank 2 or mini2 will do you good. Or Aspire line of
tanks.
Simple and not much of a learning curve with this set up. Gives you something to stay off the cigs with while you learn and figure out what you want.
Good luck and let us know how its going.
