Just a thought, as someone who has recently exclusively moved over to vaping, instead of the constant back and forth with smoking along with vaping don't kill yourself if you end up having a cigarette. It takes time to adjust, just don't give up. At the begining count the amount of cigarettes you skip by vaping. Cut the cravings until you fully adjusted by having 2 cigs max a day and get yourself a stable setup.
Me myself i started with the ego t's and moved up (spent alot of money) so I was satisfied figuring out what works best for me. I think for someone with cravings having trouble adjusting move to 24mg juice, get some boge or smoktech cartomizers from surevapes (cheap), and pickup a VV MOD such as the evic. Don't mess around with cheap batteries you end up spending more in the end. Just a hint, don't use tobacco flavored juice, they will never recreate tobacco flavors and tbo taste disgusting imho. Start with a simple fruit flavor. Just a couple of thoughts. Ppl may disagree, but take the argument of mods being for more experienced vapors with a grain of salt its only a battery.
