The reports I have recieved on GPS's is that the Etrex is good cheap and reliable

I use and own a Garmin 176C in my P/U, a Grarmin Steet Pilot in my wife's SUV, I also have a GPS III Plus, have also owned a GPS III, GPS II, and my brother just returned a Garmin GPS 38 to me.

My recommendation on any GPS you buy be at least a 12 satilite reciever as they hold receptation better than the old 8 Satilite recievers. I'm no expert on GPS's but i use them quite a bit in Search & Rescue apps.
