Hi Mark,

Well its not under $400, as they sell at $499, but I have got
a u-blox [1] Antaris GPS EvalKit running with NTP 4.2.0a and a
Linux-nano patched kernel.
You can easily order it using their online shop.

It works well with the GPS-NMEA driver and it produces
a 1 PPS on the DCD line. This is what I get with it:

remote        refid      st t when poll reach   delay   offset  jitter
*GPS_NMEA(0)   .GPS.      0 l   12   64  377    0.000   -0.094   0.001
