A six sq. ft hide sells for about $135, tanned, plus shipping from the U.S importers. The only sources of rawhide I've seen are out of Australia and they seem to be running $10 Auzzie per square foot!
I'll stick to domestic antelope rawhide for now! ...or $5 bills, they'd be cheaper.
Don't get me wrong, I'll use a 'roo hide if I can get my hands on one. To quote Pat B, "Damn you James!!!"
