So what I understand you to be saying is, the GPS-based units are expensive
because of licensing, but the radio-based units will do just as well and
are cheaper. Right? So, can anyone suggest a good radio-based unit? I'd
especially like a standalone unit that provides NTP directly, unless it is
so much cheaper to stick it in a host. Hosts have this annoying tendency
to take on more work if you're not careful... Law of physics or something,
no matter how hard you try...
