I think now is the best time to buy Starlink mini 1.
I keep mine on the roof as a backup line most of the time and take it with me when i travel.
This new version is basically limited to the mobile use only.
At least I see no way of mounting it on a roof safely. Mini 1 also can melt snow. I doubt this new model can.
There are plenty of adapters for drill batteries for Mini 1.
