dude honestly, don't let anyone steer you the way down the road of spending thousands on this if you truly do not want to or do not have the funds to do so. if you want a cig-alike to look semi "normal" outside of your home, get a PCC kit with some spare cartos. if you want an eGo or two for a good long lasting semi-inconspicuous set up, get 1-2 eGos or spinner/twists and a few kangers/clearos. If you want a nice mechanical mod that'll last you 10 years, get one with a few
batteries. If you want a VV/VW device, get one with a few
batteries for it. Get a couple of your favorite toppers, some favorite juices, and just vape! You can collect if you want but you could end up with things you don't even need down the road. Or you can build up a stock for a "vapepocalypse" but, don't blow your paychecks on that. You'll be able to vape. You'll find a way. Even if its less comfortable than
vaping is now. But the most important thing is to VAPE!
