From what i have found personally. (your milage may vary)
I love the ego, charge both batteries and i was good for all day, now 2 batts can get me 4 days ish.
i went from store bought juice to mixing my self (be careful nicotine is a poison) and it allows soooo many flavor combinations when your ready. Until then start with your pre-filled carts that come with a kit, then buy some other flavored carts. I say this because there is a routine difference between analogs (buying a pack of tobacco) and vaping, i found it much eisier to start with only having to charge a battery, pop on a cart and vape. i now mix my own liquid and direct drip and have two homemade (cheap/ugly) mods. If someone that custom mixed and direct dripped came up to me before i started vaping and said "Look what i do instead of smoking" i would have said thats too much bs to go through. However there is a natural progression and its really a routine now. start easy.
Good luck.
Oh asfar as places to buy and price. You get what you pay for. Watch alot of youtube reviews, they try alot of stuff and have good insight. search youtube for "Grimmgreen", "moobyghost", "phee303", "QCAssociates", "Doctorvapor", "bigicedog", "allaboutthevapor"
