I was equally dazzled and confused by all the variety of devices to use - watched videos and searched various web sites.
I settled on a kit primarily because I knew nothing about what I should get or what I needed (still pretty new 1 month non-analogs).
I chose the eGo-T because a lot of users liked it, it had a choice of battery sizes - choose the 1000 Mah (got two batteries in the kit) or the 650 Mah. The 1000 Mah takes at least 4-5 hours to fully charge; kit came with a wall charger and a USB connector which attaches to the wall charger and then to the battery (screws together); it came with the atomizer tank (fill the tank with e-juice which you buy separately). However, I had issues with leakage with these tanks so I purchased a Kanger T2 clearomizer which I unscrew the top and fill (carefully) with my e-juice of choice) then screw the clearomizer onto the battery. I liked the option of being able to shut off the battery while not using it (five clicks to shut off, five to turn it on) when I store it in my purse I am sure that it won't turn on when I am searching for things in there. I'm new to vaping, but I am quite happy with what I bought.
I used to smoke very mild menthol cigarettes and maybe 10-15 a day so I 1) didn't like the taste of tobacco, 2) wanted something fairly light -little throat hit and 3) something smooth and warm. I use 100% VG from Health Food store and add it to some of the flavoured e-juices that I bought (12-16 mg nic in 70% PG and 30% VG (hence the adding of additional VG on my end)).
I instantly quit smoking analogs - I would say it took about 3 weeks to get all the toxins out of my system from analogs.
Best of luck - am sure others will offer their own choices so you may end up with a variety of devices as time goes on.
