bclewis, if the PT works for you then great. I can understand your frustration about a power supply. If money isn't an issue, please look at the ProVari, Darwin (I've never owned one but people like these), and the Buzz. Voltage makes a world of difference on vapor, throat hit, and flavor production. If money is an issue, look at an inexpensive 3.7V or 5V box mod. Just because they are inexpensive doesn't mean a damn thing. I have owned many mods, not all of them, but a bunch and one thing I will say is to try one. Madvapes.com has a small variable voltage box mod for $35 plus shipping. Takes 2 14500 batteries and worth every penny spent. I bought one just to have a variable volt mod to take outside without having to worry about loosing/breaking one of my higher priced PV's. The little box hits just like my big mods. The batteries last me about 5 hours but I vape constantly...6-7mls a day so get an extra set of batteries for it if you choose to go this route.
