It seems so easy to just build a PV - check on youtube and in the modding forum here for guides on making mods from battery boxes, flashlights, altoid boxes, beverage cans, prescription pill bottles, etc. I stopped throwing away old clearos and attys - or anything with a 510 connector since I might need the parts later on. I'm keeping all my mini nova heads, too.
I bought some extra nic base - not that much, really, because I already had some and it lasts a really long time. I will probably buy 1 more 500ml bottle - for a total of 1 liter - and that keep me vaping until the nic goes bad in my freezer . .whenever that is.
