    I've had success with a Raspberry Pi & GPS.  You can build a very respectable stratum 1 server for less than USD $200, if you can handle a soldering iron and build a Linux kernel.

The RPi is nominally $35 - but add a case, power supply, SD card etc and 
it's closer to $100 - depending on what you have on-hand. You need a 
monitor, KB & mouse to get started (configured), but not thereafter (SSH 
will do).  A GPS receiver will cost about $70.  The hockey puck version 
(e.g. GPS18x lVC) is a reasonable choice and can be placed outdoors, 
though it needs a level shifter; or the ceramic MCMs (e.g Adafruit 746) 
at $40 - but you'll probably spend another $40 on antenna & battery 
backup.  It will run quite happily on an SD card; an external disk isn't 
required.  Might want a small UPS.

If you build NTP and a kernel with PPS support, you end up with a pretty 
stable server.  Doesn't use much power (~5W).

For an interface to the 18x LVC, see 
http://www.raspberrypi.org/phpBB3/viewtopic.php?f=41&t=1970&start=194

If you want multiple servers, the second one usually costs less because 
you kept all the bootstrapping supplies.

Further discussion should probably find another list...
