If you're prepared to do a little re-engineering (with a mallet, a drill, and a counter-sink), I thnk you'll be happy with the Flatland Racing skid plate. Mine has worked well for me. But they may no longer be made. Not sure.
I believe a B.C. company (Scorpion Racing?) makes a skd plate [and your US bucks should go further up here
].
And Moose makes a plate. As does Utah-something-or-other (Racing?).
I'd just search the forums here; it's a great resource.
