You can get a bluetooth GPS for a lot less than a standalone handheld model of any brand, especially one with mapping capability. You can get a bluetooth receiver for well under $50 if you look around. I have both, mainly because I bought my Garmin long before bluetooth models existed. I still use it for geocaching, because I don't want to carry my good Palm or my N800 out in the woods and the mud and the wet, risking dropping it on rocks or in creeks. The Garmin is much better suited for that, because it's waterproof. I use the bluetooth GPS for driving directions on either my Palm or my N800. Currently, Mapopolis on the Palm is far better than Maemo Mapper, but it's a much more mature application, and certainly not free. It's no longer available, however.
