Power steering fluid flush on 2000 Toyota Camry

The dealership told me I needed a power steering fluid flush. About what can I expect this to cost me?

The Toyota uses standard Dexron power steering fluid. Fluid id drawn out of the steering fluid reservoir and the return hose is disconnected and placed in a empty container as two quarts or so of fresh fluid is pumped through with the engine running. Labor about 20 minutes and two quarts of oil.
