a couple tips i have found

1 some scrap yards will take copiers as appliances if you remove the toner and green board
2 always remove the removable ic chips from motherboards usually will increase profit and wont lower board price
3 high grade boards can be found in places you wouldn't think to look
4 just because it expensive does not mean its worth a lot in scrap
5 don't forget many items also have a vintage value
6 if your not sure ask
7 removing heat sinks and large caps and transformers from green power boards usually raise there price
8 everything has a value to someone



if this helped at least 1 person it was worth my time
