When splitting component video for 4 HD sets all on the same signal. What would be an effective and lower cost solution that you may have used or know about?

This is coming out of a cable HD PVR cablebox, and is to feed a 50" plasma in the MBR, two 50" DLP's in the exercise room and sitting room respectively, and a 20" LCD in the M-Bath. Because of the X shape of this suite layout, all components are located in a central column. Thus all cables can maintain a 2 meter length.
