I am getting ready to hit that purchase button on the provari site myself. I figured I would go with the starter kit and the provari in satin silver. I have read that the colors get chips in them if you drop them and if you wear rings, they will scratch the color off. So, I don't want to spend that kind of money only to have it looking crappy in a few months. So, the silver for me. The starter kit comes with the batteries and charger and I plan on getting the extension cap and two extra 18650 batteries. I want 2 "regular" size and 2 "big" size so I have options and backups. I am very seriously thinking about getting a mini as well so I have a back up device and a third size option.
I currently have a dual-coil tank and love it, but I'm not happy with my cartomizers, so I plan on getting some Boges and some 501 fusions from Ikenvape (I hear they are really good as well). I also want to try out the vivi novas, so I will get one of those, too. I get almost all of my liquid from Awesome Vapor (18 ml for $8 - ya you can get it cheaper but I know I love it so it's worth the price).
I figure I spend $160 + a MONTH on cigarettes, so really, if I can afford that I can afford to buy pretty much whatever I want as far as trying out new vaping stuff... and bonus - it won't kill me!
