If your first kit was "cig-alike" (about the same size as a cig), I'd suggest you move up to an Ego Twist or Vision Spinner.
Then, while you are enjoying the benefits of a larger battery and learn a bit about what it is like to be able to change the heat volume, you can look at the multitude of "mods" available.
Vamo is the size of a billy club -- OK, I'm exagerating. But it is very large and very heavy. Some love those features and you sound like that's the way you'd like to go.
There are several devices that one could choose that aren't quite to big or quite so heavy at similar prices, and often less than $20 more.
It might be a good time to do some study. Check out the ECF Library. Many topics are covered there and it is wise to learn about battery safety, which batteries you will need and which chargers have the best reviews....and that doesn't cost anything.
