I have similar issue as the OP. I am considering the use of Y cables to split the signal, but I am concerned about the effect that may have on the quality of the signal. The switch box one post links to is probably no better than the old Rat Shack boxes (I use one currently). I am also thinking of using an old receiver with multiple tape loops as a (very large) input switcher. Again, though, the concern is signal degradation.
FWIW, Morrow offers Y cables at many price points that might work. I may go that route myself.
