I've got wrist and thumb issues from an old rock climbing incident 20 years ago and have invested in light and heavy duty cordless drills and torque guns from Lidl and Aldi
I always scan for stuff when I'm in for the cheese and milk to see if anything is about
They did a great heavy duty hex kit about a year ago for about 20 quid and the lighter fiver jobs show up pretty often
Lots of stuff on ebay, I tend to just suck it and see, at the end of the day it depends how heavy your useage is
I now have a torque drill toolkit with a bunch of adapters, it took a year or two to put together
