The TrapKAT XL...
I love playing this thing. For drummers who like to play electronics and want to walk in and setup in about the same amount of time as the keyboardist, this is fantastic. It's not for everyone, but I like it. 24 pads, (relatively) quiet for those who need to limit the noise, and it opens up a world of drum samples.
My kids, on the other hand, prefer to play my old Ludwig kit. That's fun, too.
