I have a Magellan SporTrak and it serves me pretty well under ideal conditions. I've been thinking of upgrading to the Garmin GPSMAP 60CSx as the reviews have been stellar, especially when it comes to reception. Their site says it has been discontinued. Has it been replaced by another model, or is there one comparable to it? I realize such a GPSr will be quite an upgrade from the one I use now, but I figured I might as well get a superior unit. Any help or thoughts would be much appreciated.
