Yay! Finally someone who doesn't come in, and have a first post that goes "how do I blow beeeg beeeeeg clouds!"
Before the crazies come in with their suggestions for you to get a mech, RDA and start subohming your face off....I'll go first!
It seems like you're comfortable with a ego sized battery (they're kinda like. Skinnier cigars.) and don't need a cig-a-like. Excellent! IMO any of the decently branded ego would be a great choice. Perhaps you could advise us on a little more details, and I can even help you search for some deals:
1) what's your budget for both your husband and yourself? This includes the starter kit and juice
2) is your preference towards pocketability or battery life? Ego batteries can go from 350mah (tiny little things) to 1300mah last time I checked. But those are decently long. If you're looking for a full time replacement for cigarettes, then buying a smaller battery will necessarily require you to have multiples.
3) this might be a stretch, but any chance you or your husband might be into a box mod like a MVP v2? It's very very safe. Affordable at 40bucks, and will easily last you 1.5 to 2.5 days.
Overall, until you give more details, I'm very very happy that the both of you guys are gonna be in this together, and your motivation is to quit the cancer sticks. The ego is a GREAT choice; don't let the ERMAGERD JUST BUY A MECH crowd sway you.
ETA: IMO you'll be fine sticking to a starter kit + juice. Of course it doesn't have to be a fixed kit per se. As long as you have the ego battery, a charger for it, a clearomizer or cartotank (NOT any rebuildables), and juice, I think you're solid. Just update on more details and we'll get you along
ETA: oh I just remembered. Could you also let us know how heavy a smoker were you and your husband, that will affect how many mg nic you'll need for your juice, and also likely need to take into consideration the expected longevity of your tank's coils. (Heavier smokers tend to chain vape like craaaaazy when they first start, so the "life span" of the stock coil is a worthy consideration)
