I'll throw out my experience starting out. I had been smoking (analogs) with a guy at work who showed up one day with an apparatus I had never seen before. He showed me his PV and pointed me to this forum. He wouldn't give me a model number or name of a product, just told me that there's a lot of different things out there that have different strong points, depending on why you smoke.
Of course, being impatient, I didn't read this forum and instead did a google search on e-cigs and came across some page ranking a bunch of systems. From what I gather now, this page was making money off of referrals. I read a little bit and made the decision to buy a GreenSmoke kit. I bought it because it looks the most like an analog and I thought that simplicity (screw on a cartomizer and get to business) was what I wanted. Once my kit finally arrived, I was very excited and charged up the batteries. Within the first day I realized that I really dislike auto batteries and that cartomizers are not for me. I have "control issues" and love to tinker and wanted a much more involved and personal experience. I kept smoking analogs, but I already liked
vaping as well.
I found a headshop locally that sells e-liquid and picked up some (pretty good, actually) chocolate flavored liquid and started reading about different models out there. After long consideration, I decided that I want something that doesn't really look exactly like an analog and bought a 510 dual kit from cignot with a PCC, black with blue led's. It arrived today.
OH MY GOD I love it. Just since I've gotten my 510 today, I've smoked well less than half the analogs I normally would have. I am a solid 2 pack a day smoker and still have two analogs left in my pack after bumming out about 7 over the course of the day. The PCC is a godsend, but I think I need more than just two batteries and I'm already thinking about a mod for a larger battery.
I've already got several other people interested in
vaping, and I would not be surprised at all if they have a 501/PCC kit from cignot next time I talk to them. I doubt that the 510 is last piece of hardware I ever buy, or even the best. I do, however, wish it was what I had started with. Also, esmokeronline has a cappuccino flavored
eliquid that I am LOVING.
Just my $.02
