Are the RF receivers cheaper than the GPS receivers at this point?
Sparkfun sells some pretty small GPS receivers for about $25.. Course,
if you're into WWVB, digikey has a WWVB receiver & antenna for $10..
although for my clock, I needed to replace the original tuned loop
antenna with a larger one.

I wonder if an adaptation of my GPS time system mught work. I have a
central clock that reads the GPS and then sends it to the other clocks
via RF. What about a central clock that sends out a 60/50 hZ beat via
RF? RF receivers are fairly cheap, and then you only have to calibrate
one xtal or whatever you use. You should be able to bodger it into
many exsisting clocks.
Sure am glad that I went the GPS route now! All my clocks will remain
synched, do DST etc.
