try making your own (very easy) with puck board. i made one two years ago and it verrry durable. i live in calgary and if you wants some pics e-mail me at outrgus@hotmail.com and i will send you some.
I think he means the "boards" of an ice rink. I believe all that is it white plexi glass 1/2" thick or so, then a metal frame ion the inside, with mabey plywood, then another piece of "puckboard"
puck board is white plexi, very durable (handles 100mph slap shots) and handle the woods riding i do even better. a little heat to bend and four hose clamps and your done. you can cut it with a jig saw. i get puck board from my local ice rink for free when they change it out for new stuff.
