If you haven't already done so, visit the Garmin homepage www.garmin.com then click on "Outdoor" and then "Product Comparison" (the latter is in the left frame of the page). This will allow you to select several units for comparison of features.
A good basic unit is the Garmin eTrex (the yellow one); however, I think once you get a basic GPS you'll wish you had the features like mapping, etc, and the increased accuracy of WAAS. I recently upgraded from an older Garmin GPS 45 to a Garmin eTrex Legend, and am very pleased with it. The Garmin Gecko series looks interesting for an entry level unit, but I have no personal experience with them so I can't offer any advice one way or the other.
I prefer the user interface of the Garmin units to the Magellens, but that's strictly a personal issue like Ford/Chevy or Celestron/Meade.
