I'm probably going to get yelled at for this by the Kanger haters, but I would steer you towards the Kanger Subtank Mini as a new vaper. It's inexpensive, reliable, very common so coils and replacement parts are everywhere, and it comes with an easy to use rba deck for when you inevitably want to roll your own.
They're like the F-150 of tanks...doesn't necessarily excel at anything, but does everything well.
