i have one of those and a couple of things to point out:
it is enormous and stands out quite a bit due to the bright colours.
it sometimes stops working of its own accord even when left undisturbed and i have to switch it one way then to other to get the connections to clear.
better solution would be if your tv / amp can act as a the switch - modern tvs have digital inputs (HDMI) and an optical out. so ps3, x360, sky etc all into the tv then optical out to the surround reciever.
plus i hate having to get up and switch it manually - i understand that there is a high end remote version somewhere.
