Hot off the presses. Check this out:
http://www.garmin.com/products/gpsmap60c/This is perhaps the coolest GPS that I have ever seen. For a few extra dollars you can also get a compass and barometer built-in. You will also have to buy the detailed auto-routable road map. Or you can install a topo map for those hiking adventures.
This product will liekly be right at $420 (plus maps - another $100), and is due out first quarter of 2004. What a cool GPS.
If you can afford it, this one would be worth waiting for!
