If you want mega-cloudz and don't care about your juice bill and want some flavour, you could look at the Uwell Crown (V2 is just out) and the SMOK TFV4 both of which take factory coil heads and also have RBA sections available for them for rebuilding.
Personally, I'd just rebuild and forget about the premade factory heads, as they're expensive, don't last that long, and might be unavailable especially in far flung places where 21st Century vaping hasn't quite reached yet. Something like the Sigelei Moonshot would do you proud:
You can get a decent clone Moonshot from Fasttech for around $13USD:
For a dripper, something like a Kennedy clone ($10USD @ Fasttech) would suit I would imagine, but I'm not the authority on DTL drippers, so maybe someone else might have another suggestion.
There's nothing wrong with the Kennedy, though.
