FWIW, you can't go wrong with Meinberg. Several versions to choose from, reliable, and priced well.

I can't roll my own in this case. At home I have a Soekris box with a custom built gps board for my normal level of time-nuttery but this is not for home. I'm looking for commercially made rack mount servers that will not have Internet access for reference and will need to rely on gps. The system will need to serve time to less than 100 systems but it will live in a nasty environment in the back of a humvee (or something like an S-250 electronics enclosure) with no air conditioning of any sort. I'm currently looking at Symmetricom, Trimble NetRS, EndRun, and Meinberg. Also, I apologize if I'm breaching protocol with this thread. This is just about the first post I ever saw on this list that didn't get a steady stream of replies. I was actually questioning if this even made it into the list till I saw this reply. Yes this is for work and I could really use some opinions on this stuff since dropping $4-6k isn't in my nature to do at home for a network clock so I never gave this thought before.
