Home only: I've used all kinds of cutting boards (I even found my wife using a glass one - once...) and I'm a believer in plastic. You can get 'em big as you want and they're easy to store and move around. Yep, they get cut up and I'm sure bacteria can hide in the cuts if you don't clean the boards right. So...clean the board right! I scrub with a dish cloth and soap, rinse, then spray with commercial bleach cleaner. Lean it up against the sink's backsplash and let it air dry. I've had no funky taste, ever, and discolored spots fade away like magic.
For the record I've never tried bamboo. ;)
