When I bought my house I went deep into battery powered tools (Ryobi, but I think its all similar). I have 2-3 drills and 2 impact drivers. It is really nice to not need to change bits often, and with my ADHD having a few sitting around in the room where I'm actively doing heavier work is nice too. Lots of batteries, handful of other tools from them.

Having multiple of some seemed very silly, but it really is so useful!
