Summary: I really like this model. I had to replace my old one because the screen got sctratched so badly in my ATV bag, you couldn't read anything and the cost to fix my original was going to be more than I wanted to spend. This is a great middle of the road GPS unit.
Summary: I bought the Etrex used and in good condition. The unit worked as advertised, but the Garmin instructions leave a lot to be desired. Luckily there are forums on the web that can answer questions more coherently. I use the unit for tracking and setting waypoints.
Summary: The Vista is an older model but has the additional bonus of an electronic compass that is usable without moving. It does have known issues, notably that the date sometimes doesn't function properly.
Summary: I got this product for Geocaching. It's been very accurate and precise. The functions are easy to learn and use. The screen is very fine which makes for up close and personal looking. Batteries could last a little longer. Over all a great tool.
Summary: I have been using this GPS since November 2006. I purchased the cable from Glisson Technologies for my D7A and it works ok. The only issue I have is the unit turns off after a while without the APO being turned on. I have to press the button to bring it back on line. Otherwise, good product.
