Toslink Audio Switcher

I have a PS3, Direct TV H20 and TIVO that all have optical digital outputs. My Onkyo receiver has only 1 optical digital input. I have been searching for a quality Toslink Audio Switcher. Here are the one's I have found:

Digital Optical Selector Switch - Dayton Parts Express

3X1 Optical Audio Toslink Bi-Directional Manual Switch - Monoprice

DIGITAL AUDIO EXPLORER TOSLINK SELECTOR SWITCH - Impact Acoustics

These are all manual switchers. I am looking for input on these switch boxes or other switch boxes that work well.

Thanks Rupert, I saw that switcher when searching the internet. It is more than I was planning to spend but you do get what you pay for. I am also looking at the IMPACT ACOUSTICS 3-PLAY HIGH PERFORMANCE COMPONENT VIDEO/DIGITAL AUDIO SELECTOR.

Has anyone tried this product or products from Impact Acoustics?
