The post made by Jazzi Mike on the first page of this thread is exactly where I bought my Vamo V3 several months ago (
FastTech). The stainless finish will last you longer and not wear easily. It usually takes 10 to 14 days from China in my experience. Well worth the wait for the price and for what you get in the package deal. The Vamo is a great PV for beginners and for veterans alike. It's simple to operate, reliable, and the price is definitely right on ($58.85 at the time of this post). I use it more than my Segelei Zmax V3 telescopic PV because of how easy it is to change the wattage (1 button press vs. 6 or 7 with a menu wait time with the Segelei Zmax). The NiteCore charger that comes with it is supposed to be a decent "intelligent" charger (won't overcharge/overheat your batteries and reduce their life span). Just be cautious with some of the FastTech packages because not all of them come with that charger. If it doesn't say "NiteCore" in the description, it's going to be a cheapo charger. Also, don't get the one's that say "Euro" in the description or you'll get the 230 VAC version, no the US 110 VAC version. The batteries in the FastTech deals are cheapo's with smaller mAh ratings, but will get you going until you get around to buying better ones. The Vamo V4 is supposed to be out now, and FastTech may have a similar package deal with that one as well (although I haven't verified that myself). If I had it to do over again, I would jump on that Vamo deal without a second thought or rearward glance. I would recommend it to anyone and I think you'll be quite pleased.
As for the tank, I've only ever used the Viva Nova, but I just ordered the Kanger Pro Tank 2. I think you're on the right track with that decision (get the Pro Tank 2, not the original Pro Tank). I like that it's bottom-fed since I'm fed up with having to top-off the Viva Nova with e-juice to avoid that slightly burnt taste that seems to start happening when the tank is only 10-20% empty. What's the point of the large tank if you have to constantly top it off? I'm hoping the Pro Tank 2 will solve that without introducing new issues (flooding and gurgling?). I guess we'll find out soon enough... Apparently most people are happy with it.
Best of luck and congrats on tossing out the cancer sticks!

Vape-on!
