Our team used a debouncer last year, because we've had issues with buttons in the past (notably a joystick trigger in 2005, where sometimes it would see itself flipping on/off very quickly and try to actuate a pneumatic cylinder equally as fast).

I plan on using it again this year, and for the magnetic reed switches on cylinders in addition to buttons.

However, whether or not they are necessary is entirely dependent on how you control things, and whether or not your team is having issues with buttons. It's not difficult to do, but if there's no problem, those few hours on that are better spent elsewhere.
