Generally Combo Microsoft or Logitech sets with an occasional big box generic (wired) just for testing use or for use by younger family members.
Use both wired and wireless - prefer wireless for the most part.
Biggest problem as of late has been the lettering wearing off of the keys. Even the more expensive keyboards do that now. Solution: stickies or white marker for the non-touch typists.
Rotate through about one of four keyboards/mice per year through breakage, wearing out, or I give an older one away from time to time as warranted.
