Might be a dumb question, because I have never seen both together in person, but will the Mini and Midi tops interchange on the lower tubs? The specs all seem to be the same, except for bag capacity? In the previous pictures, they look the same, other than the height of the tub.
I can definitely see the point of the Mini if you have a particular space requirement and if you are just using it with a TS, SO and occasional sander, it won't fill that fast. Those things make smaller chips/dust.
The cord wrap and accessory handle are rather subjective. Mine (CT26) is in a static position, in a cubbie hole. The handle would not work for me and the cord is always wrapped up.
In my situation, the Bluetooth remote is the most valuable accessory. If I had it to do over, I would probably get a Midi, purely because of cost though. The Bluetooth module is an extra with the CT26 and those newer Mini and Midi were not available at the time, I got it. The CT26 is great and I'm certainly not disappointed by it, but either of the smaller units would do the same job for small chip tools. TS, DF, RO, MFK, etc
