However, only the most recent and most expensive receiver/amps will have YPrPb component video switching...
The cheapest home theater receiver on Crutchfield can do component video switching between two devices. Of course, that doesn't mean it's good.

I have a Sony STR-DB1070 and the component video switching works great! I know that page says MSRP is $900, but I didn't pay that new about a year ago. I remember closer to $600. I think the entire DB line is discontinued now though.
