In my case I wanted to quit analogs for obvious reasons after 20 some years, but also to adjust my budget. I started with an itaste vv3 and then picked up a cheap clone evod batt as a back up. I managed to break my v3 (my fault) and bought a vision spinner 2, then most recently an Itaste mvp 2. All in all I find I don't need more than what these have given me. As far as tanks go, I have simple evod, kpt2 mini and most recently a Ehpro clone of the kayfun lite+ (rta). I bought it with two things in mind, 1- it was under $30. 2- I don't mind building my own coils if it meens I can save money. So far I've been able to do that, but my goal wasn't to keep up with the cool ppl, it was only to keep myself on track to stay off analogs! At the end of the day, that's what matters. We all find or goal in our own way, and it's a beautiful thing!
