I went to that site and didn't really see the product - but it sounds like it's plexiglass. Even buying plexi at the hardware store is a tad pricey (would you believe it costs more than glass?!?). Still, if that's what you wanted, I'm pretty sure the local hardware store could cut ya some and it'd be cheaper than ordering from that site, especially since you could buy a few and try them. If you liked 'em, you could always space out your purchases until you had all you needed.
