That's easy. But you have to get over 2 things that newbies always do and are almost always the biggest mistakes.
The first is wanting an e-cig that looks like a cigarette. You will soon be a non-smoker. Little e-cigs have serious limitations with battery life and capability. That's probably the single biggest thing that sends people back to analogs. Battery life sucks, and there is nothing any manufacturer or fancy package can do about it.
Second thing is an automatic battery. Don't fall for it. It will take you 3 minutes before pushing a little button will be second-nature. Manual batteries are more reliable and controllable than automatics. All serious PVs have manual batteries and there is a reason for that. Autos are made to appeal to newbs who find it a strange concept to push a button, just like that stupid light on the end of some e-cigs. It's a gimmick and unless you want to vape while you perform open heart surgery, it's totally unnecessary.
Any kGo/e-Power PV is a two piece unit. You have the PV and a cartomizer, just like you have a V2 battery and a cartridge. If you want to add extra stuff, you can do it, but it's 2 pieces. Some come with a cone, but that's just a cover you screw on to streamline the appearance. These are not large units. They're about the size of a Sharpie marker pen. The batteries will last you most of a day, they provide the voltage you need for a good, satisfying vape and they're cheaper than any V2 kit.
There are several very good vendors that sell kGo and e-Power kits. The difference between the two is that the e-Power takes regular batteries, like a flashlight. The kGo has a sealed battery inside. When the battery gets old and weak, as all batteries do, you throw the kGo away or buy a new $5 battery for the e-Power. Other than that, they look and perform almost identically.
You can get an e-Power for $57 shipped, including atomizers for tasting juice, cartomizers for regular vaping, 2 14650 sized batteries, a charger and free PRIORITY shipping from crystalclearvaping.com They also give you 30ml of free e-juice. Order it today and you'll have it by Thursday. It includes everything you need to start and to hold you over for a couple weeks until you get more juice. You can get extra juice and cartomizers there and shipping will be free for that as well.
CCV has an excellent reputation. They don't have a huge selection because they only sell stuff they personally use. That's the way that site was started and that's the way they have kept it.
I don't mean to sound like a commercial, and I have no interest in CCV, but if you want to cut through all the confusion and deal with someone reputable, you can't go wrong with them. You just have to get over that "looks like a cigarette" psychological block. Companies like V2 and Blu exploit that and rip you off because of it.
BTW, feel free to PM me if you want any more detailed info or have any questions. I'll be delighted to walk you through it all, but I'm done sounding like a V2 affiliate.
