There is no other expense, unless you want to get into tying in your location to map data from a non-free source. I use an older Holux puck-type receiver, similar to your first selection. Since my upstream is somewhat flakey due to the variable latency problems introduced by my incompetent last-mile provider, I provide my own NTP stratum-0 reference clock from the NMEA stream.

having never messed with GPS software running on linux, one or two
truly beginner-level questions. if i want to simply buy a GPS receiver
and set up my fedora laptop to start receiving raw NMEA data, once i
purchase the receiver and install something like gpsd, is there any
additional expense in terms of a monthly service subscription or
anything like that? (i warned you this would be a dumb question.)
i'm interested primarily in experimenting with receiving/parsing
NMEA data, the kernel modules involved, etc., so i don't need
spectacular performance or precision. i'm in california next week so i
figured i'd check out these two USB GPS receivers:
http://www.embeddedworks.net/satl114.html
http://www.embeddedworks.net/satl116.html
then i'd install gpsd (or equivalent if one exists), fire up a client
and start reading data. is there any more to it than that? also open
to recommendations for other GPS receivers if anyone has good
experiences.
