If you decide to PIF any of the stuff, I'd nominate my parents. I converted them. They are seniors. They don't do interwebz. I order/mix/build everything for them. They are happy to fill a tank, press a button and not much else. As they are on a fixed income, it's not easy for them to budget expenses like back-up batteries and such. I'm not in much of a position to support 3 vapers, myself, either. So, just sayin', if ya wanna help some seriors...
