First off welcome and congrats on taking the first step to becoming better informed about e-cigarettes and vaping (we are not smokers

no smoke, just vaper, we are vapers)
now onto the nitty-gritty, keeping in mind that vaping is a personal choice and what you pick is something (hopefully) you will be using all the time and for a while
Please give us more information of what you are wanting and we can help point you more to something to fit your own needs.
Are you wanting something that is like a cigarette (like the blu but better) or are you willing to step out of your comfort zone a bit and go for something that works better but looks nothing like a cigarette?
I started with 1 NJoy and then got a blu kit, while the blu kit worked alright for me there were it's flaws. I know a lot of people have issues with the battery but then that will be an issue really with any cig-a-like (anything that looks like a cig) and for me when I took a puff off of it it was too airy so I had to keep putting tape around the connection covering all but one of the air vent holes to get a good drag.
If you are willing to step away from the look-a-likes in my experience and from most what I've read I'd suggest a spinner, it's about the size of a highlighter.
I would suggest a 1300 mAh variable voltage spinner. The higher the mAh, the longer the battery lasts and variable voltage means you can change the voltage output to better suit your taste, different juices and different juice delivery systems (cartomizers, tanks, ect) taste better at different voltages.
