Ours are all Makitas and we always buy the same brand so the batteries and chargers work. My next addition will be an angle drill.

I have corded tools too, just in case but other than the corded circular saw I seldom use them. I had to build a sloped floor in the dairy and needed to rip some 2x4's for bracing under a sloped drain and the battery one just couldn't rip 12' of 2x4. I didn't want to use the table saw as the boards went for 3" to 0" in 12' so I freehanded it with the circular saw; easier to get that angled cut.
