You might want consider a Kanger Subtank mini also.
They really are excellent for the price.

Decided to try my tobeco kf4 with ni200 tonight.

Still adjusting the settings on the dna40 to see where I like it with the kf4. I feel like I need more airflow, especially coming from using a STmini all week, already drilled center post to 2.78mm, but may try hacking it up a bit more.
I did the reverse the AFC grub screw trick to get around the janky spring.
