I would ask, no BEG for the new chip set in a basic GPSr like the GPS 60. I am a simpleton and don't want or need the color or the maps. I like the speed of th processor in my new 60 but would love to have it with the ability to keep a lock under a pine tree!!!! My old GPS 12 keeps a lock a little better than my new 60 does, no matter how I hold them. But the old 12 is just way to dang slow. If you stop it takes several steps for it to realize that you are moving, and you have to keep moving fairly quickly through the woods for it to continue navigating.
