Why aren't ISPs providing stratum 1 NTP service?

  I looked into setting up a WWV based refclock a few months back for a
client. We were unable to find a WWV capable clock for under a few thousand
dollars. The old Heathkit one ($300 or so?) was no longer available and all
of the other ones I found mentioned in the xntp docs were in the thousands. 

  You mention using a GPS clock, while I've been looking into WWV. Can you
point me to some, hopefully inexpensive, hardware that we could use to
provide this service?
