Ferg,
Garmin has quite a number of units which output your needed $GPRMB
sentence. Unfortunately, many of the smaller units (Colorado, Geko,
Foretrex) are discontinued. But there many other units which output the
sentence.
I'd suggest you go to the Garmin Support site (
http://support.garmin.com/ ) and enter NMEA GPRMB into the "Search" box
in the upper right. This provides a list of 106 hits. Many of these
are hits on the same units but you should be able to sort out the
various devices and then look at them individually to see which may be
suitable for your task.
Trying to find a GPS unit by NMEA sentence output is a very difficult
way to search. You might try other GPS vendors and see if a similar
search facility is available.
Good luck,
Bob Borger

are profligate and sit in many cell-phones, i-this=92s and e-thats.
