I just got a Garmin GPSMap 60c and it is great. Routes very easily, uploads maps quite well and EdgeGPS.com had it for $155 on EBay. They are very easy to deal with and ship EXACTLY what they show. I have yet to go Caching with it, but plan to this coming weekend. I have a Garmin ETrx for my two boys to learn on, and I also have a Garmin IQue 3600 PDA that I use daily in my car for guidance. The Garmins seem to be a bit smaller and easier to handle to me than the Magellans.
As you can see, I like Garmin. The Magellans look nice, but I have not used them at all, so I cannot speak to their ease of use.
Being as this is my first post, and I don't even have a cache under my belt, take this for what it's worth.
