I couldn't help but notice in your sig that you say "at this this rate I will never break even!" I'm going to assume (especially since you've been a member since 2010) that you've probably tried several types of pv's. Well, I suspect your search is finally over. You said this was the best device you have gotten so far. That's exactly what I said when I first got my provari. I've had it nearly a year now and I'm still saying that. Once you get your tanks, I bet you will be able to settle in comfortably with your setup and you will find that you may actually break even.
