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!!!"
