Hello, my aunt is looking to buy my uncle a gps for xmas (so he will b able to take his grandkids caching) She has a $100 budget. Wot is a good site to compare units??

REI will let you view units in a side to side comparison on screen.

With a budget of $100 it may be difficult to find more than one GPSr to compare. The Geomate Jr. might be the only unit around that price that has strong geocaching support.

Going to be an Etrex or Etrex H if you can find them anymore.

many thanks :-)
