Offset on an Intel Atom with a GPS 18 LVC here is well within 10 
microseconds, FreeBSD 8.2.  I would expect the Sure to be similar.


associd=0 status=0419 leap_none, sync_uhf_radio, 1 event, leap_armed,
version="ntpd 4.2.7p255 at 1.2483 Fri Feb 10 06:04:36 UTC 2012 (1)",
processor="i386", system="FreeBSD/8.2-RELEASE-p6", leap=00, stratum=1,
precision=-19, rootdelay=0.000, rootdisp=1.180, refid=PPS,
reftime=d3095c8b.e6660497  Tue, Mar 13 2012  5:41:31.899,
clock=d3095c98.0f62614f  Tue, Mar 13 2012  5:41:44.060, peer=8406, tc=4,
mintc=3, offset=0.003, frequency=27.803, sys_jitter=0.002,
clk_jitter=0.003, clk_wander=0.003, tai=34, leapsec=201207010000,

Even on Windows it's within 50 microseconds (by eye):


You could update to the latest ntp.
