Hi Twisted and welcome.
Here are a couple pointers...
Move into a mod you can grow into, but is easy to learn and inexpensive.
It should be regulated and support a removable 18650 battery.
The eLeaf Pico and various Joyetech mods are an excellent place to begin your search. There are gobs of great mods out there.
For your tank, I would suggest something that supports an eco-system of coils. That is what you're really buying...
What I mean by that is that certain coil head designs over time, due to their popularity, have been adopted by mannny tank makers.
Both Aspire Triton and Evo coils fit in dozens of tanks made be other companies.
And there are gobs of different coil head designs and resistances for it later when you're ready.
Remember, the coil head is what your vaping, It's nice to have a tank with sooo mannny choices in coils.
I'd say get an Aspire Evo tank.
