Hi All
First post, but have found loads of info on this site.
I just picked up some 4 x 8 x.050 clear anodized aluminum from the Redding Ca factory of SAF it is listed on their surplus page and was about $35 a sheet.
they don't do the free shipping at 100lbs for this stuff but at that price it might work out to pay shipping or if your in northern California arrange to pick it up.
Real nice people to deal with.
Tom
