depends on how much you wantto spend on a GPS unit. But, in reality they are all basically the same, just more bells and whistles on the more expensive models. A basic Magellan unit will do nicely for you and they are realatively inexpensive.-walt
Etrex Legend and Etrex Vista are both good. Legend can be had for under 300 and Vista might be able to get it at 300. I bought mine off of eBay without problems and use it often. A good way to learn the ropes with it is to check out www.geocaching.com and play there for awhile. The Magellan sportrak series are also good....
