How much should new rotors for my 2006 honda civic cost?

I ran over a metal coil and I believe I bent or shot my rotors, as now whenever I drive the car there is a metal on metal sound. I'm taking it to the shop tomorrow, but I didn't want to get reamed on the price. Also, should I take it to a regular mechanic or honda specific? i'm thinking the honda specific might be more expensive.|||if you bend a rotor you would know it either you would have no brakes or it would shake im sure you bent something.... rotors vary in prices best to call a parts store and ask any shop would do besides a dealer which would about double your price
