I have the etrex basically b/c I wanted a no frill navigation tool and the price was right. I have noticed on occasion it takes awhile to locate the sats. but it hasn't ever caused me any real grief. I have been very pleased with my garmin etrex and it has functioned exactly the way I had hoped and for my personal intention. Which I think lends itself to satisfaction for a lot of products to different individuals. It will never be my only navigation tool in my pack but it has become a great asset and tool for the low investment
