Actually the baby monitors tend to be in the 47Mhz band, but yes they
still suck.  There are newer models in the 900Mhz and 2.4Ghz range.
However, reviews of the 900Mhz models are almost unanimous in declaring
them to be worse than the 47Mhz models.  While my experience with 2.4Ghz
phones indicates that they will trash most 802.11b networks.

So, I'm trying to move away from the wireless solution.  Mainly, due to
the interference between the two locations.

The three station FM solution looks promising.  That is if it can deal
with the stations being on different breakers within the same residence.

Several reviews of this model indicate severe static problems.
