I don't know if this has been said yet but what I might reccomend is to get the Joye 510 with a Portable Charging Case. That way you get the look of a cigarette, you can hold it like a cigarette, and you can flick it like a cigarette while you get used to vaping + not have to deal with the 2 hour max battery life a normal 510 will give you. The PCC will keep you going all day and then some. Also the 510 connection is the same exact fitting as an ego. So once you get used to vaping you can simply buy an ego mega battery and a charger and you're good to go.
ALSO filling your own cartomizers is easy and does not take much time at all. Usually I fill 3 in the morning(literally takes about 20 seconds per cartomizer, a noob might take 30)and carry them with me and they last all day. but that also normally turns into me not being able to wait until I get home so I can drip . Type in Cartomizer condom filling method on youtube and you will get over 20 videos showing you the quick, easy, and painless way to re fill.
Everyone on here will yell EGO EGO EGO at you all day but honestly if I would have started with the ego I probably would still be smoking(maybe not who knows...the thing rules). But I liked having that looks like a cigarette, tastes like a cigarette ect feel for that first week just to give me that extra feeling of reasurance that this thing I was vaping on was a cigarette. It helps.
Like my girlfriend loves the concept of vaping and the taste but she hates my ego. I have even found some problems with it. You can't hold it like a cigarette, can't flick it, can't hold it in your mouth which are still things I want to be doing. But after getting through that first week with the cigarette looking one the pros outweigh those cons greatly and I love the thing.
Do some more research, do a bit of youtubing, and read around on here to decide what route is right for you. If you want a cigarette looking one get the standard 510, a PCC, some juice, and some cartomizers and you are good to go!
