What'd your budget?
There are alot of good simple mods that are all in different categories when it comes to nice. If you want a really nice mod with one of the BEST warranties in the business the price of that mod might not be the same as something like a 30-40 dollar box mod from china. At that point you're sacrificing build quality, warranty and other things.
If you say budget isn't a factor, I'd say for your style of vape try a
Radius 1-40w, OLED display, non-TC, very simply, rapid charging, VERY high quality, one of the best warranties you can get in the US and on top it's 100% American made which you won't find anything else on the list that is. Then again it's pricey, you pay for all that but this thing will last you years, same people that make the Provari.
