omg I don't know if I am glad or to sad to say this but I got you almost beat here in town but only in town 41miles away is were I take most stuff but here in iowa at local yard no names for being nice since I love the people who work there.

steel $110ton prepared $130
#1 copper no bb class at yard $1.90 #2 $1.80
#1insulated $0.70 #2 0.55 the rest class as mixed all goes for $0.40 xmas 0.17
stain and brass not sure of have not taken in this week
ext alu $0.42 reg clean alu $0.30
batteries are higher were still at $0.25lb
motors if you mean electric is only $0.12lb trans 0.10
they wont even buy power supplies unless at tin price not even trans price as they say there is not enough in them to buy them

this is why I only take steel there unless over 1500lbs and only other things when its just picked up and need space for higher value items
