nice review Chazzman!
i've been vaping for about a month now, and i just love my 510 from cignot. i have a PT since i'm in front of my computer pretty much all day, and i haven't had any problems with it. i too have heard stories of computers getting fried because of PTs, but i think that if you have an updated computer with a USB 2, you shouldn't have a problem either. you can always just get a USB wall adapter too. i actually have an adapter for my car so i don't have to worry about using up my batteries on long car rides. i think they're so convenient!
here's a thread about someone's work computer that got fried.

+1 for cignot's BASIC juices! in fact, all my straight VG liquids are from them and they're fantastic. i prefer VG for the vapor production since i find inhaling heavy vapor much more satisfying than a throat hit. if i have my computer room door closed for an extended period of time, it looks like i hot boxed the place!
although that's not to say you shouldn't experiment with PG/VG mixes to find what you like best. Ms T's Bakery and Tasty Vapor have excellent liquids that are hand made to order, and both have a niche for mixing a good ratio. you can actually request a certain ratio from TV as well.
like your sig, it really is all about the juices! i think trying out juices is just one of the many highlights of vaping.
