I *despise* relays for many reasons... they are large,
mechanical, power-hungry, unreliable, can suffer from
contact bounce, etc. etc. etc. I would take a look at
the CMOS quad analog switch, I think the number is
4016 (4066 maybe? don't have the databook handy!) for
the integrated circuit... it is basically a low-power
solid-state relay. Radio Shack outghta have this chip.
It has four individual, isolated analog switches on
one 14 or 16 pin IC. They have a small internal
resistance but I don't think it would be a problem in
this case...
