Andersen patio door handles

We have installed a new patio door a month ago. We had covington antique brass for the hardware. We would like to change the antique brass to the covington oil rubbed bronze hardware so it matches the rest of the doors, light fixtures, etc. We checked with the lumber yard where we purchased the patio door and they said it would cost approximately 325.00 to change the hardware. This amount is not feasible for me and I was wondering if had anything that was less expensive. Thank-you.
