Honestly, the best purchase isn't always the cheapest one, FWIW. You can get great service from chinese companies, as well as not so great service from US companies. Greenhouse one offers 1 year warranty on ALL their products, even attys. Their shipping is $15(which is only slightly more than I paid domestically for my eGo). There are also great US suppliers, like SmokeStik. As long as you continue to purchase cartos from them, there is a lifetime warranty on the batts. A cost of about $30 a month, and they are the closest to a "real" cig that I've had from a PV. Even though the initial cost seems high(well worth it though). The point is, there are as many types of vapers as their are PVs on the market. Some just want that cig-like experience, some want high-voltage/low ohm/high watt
juice boxes. And some
buy the best PV on the market(Like the GG). There is no way a new PV user can take advice like "spend this much here" and it just fits them perfectly. All we can do is offer advice.
OP, I'll have to try some of the BWB. I've heard good things.
