given that you trust the US-government (well, ...) you might use your own stratum 1 server using a Raspberry Pi with GPS.

here is a well done how-to:

I still need some spare time to get it running, all parts are here, but within my office location I have a bad GPS signal reception, so I have to do it at home.

So build your own stratum 1 server (maybe a second one with DCF77 or whatever you can use for redundancy), off from these servers build 2 or more stratum 2 timeservers for redistribution to offload your stratum 1 servers.

http://clepsydratime.com/Products/Time-Server-NTS3000 is a cool alternative. They are located in Poland, IIRC. And this box sells for less than 2,000 euros (this price is 2 years old). And it gives you GPS (USA), Glonass (Russia) and DCF77 (land based).

One of the best Timeservers are sold by meinberg.de

just my 2 euro-cents.
