WOW, those prices seem very low. I feel bad for all you guys that don't have a local e-waste buyer. I take the boards out of power suplies and get .40#. I get .32-.35# for motors (bm). What does your yard call mixed aluminum, I have never heard of mixed aluminum but .50# is not bad. I have been getting .45-.50# for clean cast and clean sheet. .25# for dirty cast and dirty sheet, .65# for clean extruded.
