I'm not sure about window-mounted antennas. I've seen disk
antennas that should be roof mounted running about $300. (Think
something maybe 6" across and about an inch high, very roughly.)
You need a good view of the sky because you need to be able to see
at least three GPS satellites to solve for lat/long/time, but any
additional satellites will give you better accuracy.

100ms still seems high, says the guy who just noticed that I'm
about a second off. (But my cable modem was down pretty much all
day yesterday.) My numbers are usually in the 10-20 msec range.
