I don't wanna talk about that part. I started in March with a single mod and a bottle juice, budgeting for some future coils and juice. I now have 6 mods, a dozen atomizers and all kinds of building gear. Being a techy guy, I got hooked on the hobbyist lure.

To the OP, VERY smart coming here first instead of a local shop. Local shops are hit and miss. Some have knowledgeable staff who will know exactly what you need, not try to oversell you and take the time to make sure you know what you're doing best they can before you leave.
Some will know what you need and still try to oversell you. The worst will have no idea what they're talking about, oversell you and send you home with more advanced equipment than you can handle just starting out, with little or no instruction and practically guarantee that your first impression of vaping will send you back to the cigarettes. I've personally witnessed this while standing in a shop here.
As others have said, a simple pod system like the JUUL is a good start and maybe that's all you need or want. People are different. If you like electronics and science and computers and stuff like that, you may find yourself, like me, becoming interested in going much deeper.
I never did smoke. I HATE cigarettes. Always did. I did however chew tobacco for a long time and quit that like 8 years ago. I like nicotine, I just can't stand the delivery systems. Toward the beginning of the year my niece got a regulated mod with a very good sub ohm tank (Valaryian) and showed me how to use it. It was WONDERFUL
Naked 100 Brain Freeze was the juice she had at 100 watts. Berry flavored menthol. Taste great felt great and shortly thereafter I got my first setup.
Don't know how I got on all that, but there it is.
