I would go with an E-Power, Riva, or kGo. Any of those would give you a great PV that is easy to use and fairly inexpensive.
I have an E-Power and love it. Everything is replaceable so it keeps costs down and batteries are cheap. E-Power batts cost $4 compared to ego/Riva/kGo batts that are $14-20. The batteries are 1050mah and you get 2 in a kit. I get about a day to a day and a half on one battery.
Like madjack said, Hoosier ecig supply has the E-Power for a decent price.
If you do decide you like the E-Power than I would wait till Monday and order it from Crystal Clear Vapor. They dont have them on the site right now bc he is waiting for the new springs to come in for the kits. The new springs are goldplated, longer, and stiffer. Also CCV has the new switch and Hoosier doesnt. The new switch has a 5-click on/off feature and a white LED instead of the blue. I talked to him today and Andrew said the new springs will be in Monday. I also think its worth waiting bc CCV gives you a bunch of free stuff with the kit. Its $57, so $12 more than Hoosier, but you get about $25 in free stuff so its def worth it.
You get a free 5-pack of Ressurector cartos, a free 30ml juice of your choice, and free shipping. Plus put in "ecf5off" and youll get 5% off the order. Def a great deal and that would give you everything you need to get going.
The Ressurector cartos are awesome and produce great TH and huge amounts of vapor. They hold 2ml of juice so you wont have to refill often. Its an easy to use ecig that packs a nice punch for an affordable price.
Regardless, if you dont want to wait the Hoosier deal is not bad at all, but for the new switch, better spring, and all the extras I think its def worth the wait
