I am unsure which country you are in but the UK supplier
http://www.galleon.eu.com/computer-time-clock.html has a range of
reasonably priced units that may fit your requirements.

For an inexpensive "NTP for few hundred dollars to get better than a
millisecond" end of things, I think the integrated GPS antenna/receiver
with a suitable computer right next to it is the way to go. Then you're
just running a network cable and power.
I paid $36 for two Motorola Oncore receivers. These are 55 nanosecond (1
sigma) timing receivers. I think today they cost about $25 each. I paid
$27 for the timing antenna that is a helix the inside a pointed redone.
The dome has screw holes that fit a common galvanized pipe flange. This is
not an expensive setup and the parts are all there on eBay. You need to
add a power supply. I use a plug-in power cube.
But as I said. Use what you have all GPS receivers have more precision
than NTP can make use of. You don't need high-end gear if the requirement
is only "sub millisecond".
Mostly I'd say don't spend money on performance you don't need but in some
cases you get great performance for less money.
