I too currently have an eTrex Legend that I received for Christmas.
It came bundled with a case, serial interface cable (for down loading), a holder for installation on the dash board, and Map Sorce Topo sofware.
Not sure what the cost was since it was a gift. I've been out a few times since Christmas and have logged 4 finds and 1 not found. Good excuse to out and hike around with my dog.
Used one of the eTex yellow models that Guyute1210 was refering to for the first time at Camp Jeep. Its not all that bad, but like Guyute1210 states the Legend does provide the user with more info; that and the fact you can down load Topo maps and Street Maps to it. IMO I perfer the eTex Legend over the yellow basic eTex. It's a good entry level GPS for geocaching. and my ncurrent needs. You might want to check out the web site
www.geocaching.com for more info on how to buy and what to look for in a GPS unit.
Good Luck and enjoy.
