hi Elipse2Be and welcome to the forum. I'd recommend the iStick 30W (2400 mah battery life) or the iStick 50W (4400 mah battery) for just a few dollars more. ISticks are really easy to use, and you don't need a separate battery charger and batteries. For a
tank I'd recommend the Aspire Nautilus Mini or full sized Nautilus (BVC
coils), they are top of the line in my opinion before you go into sub ohm
tanks.
Good luck in your journey.
