@RamShot Rowdy as
@Eskie mentioned if you are looking to for a new DNA device I highly recommend getting something with the 75C board. Not only are there more things you can do directly on the board, they also added a dedicated "Select" button with makes doing things a LOT easier.
I personally have the HCigar 75D (which uses the DNA 75C board). It is a small device for a dual 18650 battery mod. It is sort of a triangle shape with well rounded corners so it fits very nicely in the hand. Kind of like a flight sim style joystick. This may be the first device I ever buy multiple of for backups. Since this is dual battery I do suggest buying at least 4
batteries for it (2 sets of married
batteries).
For the topper IIRC the Squape is a MTL
tank? If so you might consider the new Ares RTA, the Cthulhu RTA, or the Digiflavor Siren. I have not personally used any of these but people here on ECF seem to recommend them a lot. If you don't like rebuilding then maybe try the Zenith from Innokin.
