+1 for the Teensy (a lot of newer Arduinos can also act as a HID)
The MakeyMakey would work but is overkill because it's designed for sensing capacitance rather than a key press.
Actually, if you have any modicum of skill at soldering you can easily use an old keyboard. I turned a GuitarHero guitar I found at Goodwill into a Frets on Fire controller that way.
