I have the etrex yellow that works with gpsbabel (on command line). It
can upload/download tracks and waypoints to .gpx files, with gpsbabel
handling the conversion nicely.
Last time I looked the basic etrex retailed for about £65, and would
help you in the situation you described. It draws a track of where you
have been and then you follow that back.
Do Ordnance survey grid references begin with SU? I'm not sure if the
etrex can do this - will check when I get home tonight, unless someone
gives the definitive guide before then.
