My Lorance has an "easy" mode and an "advanced" mode. I always leave it in advanced because there are a couple features there that I use a lot. I'm not sure if easy mode would give enough functionality for you, but it might be worth checking.
I doubt there's an idiot proof GPS made anymore. The durn engineers that do the programming think that every bell and whistle has to be added to every model. The biggest differnce I've found is how well I like the user interface--they all do pretty much the same stuff.
My new one is a Lorance H2O with color screen. It's pretty big, as "pocket" GPSs go, but it has a large screen the interface isn't too bad. Added benefit: it's waterproof so I don't have to worry about taking it out in lousy weather.
The other problem with GPSs, and virtually all electronics I've ever run across, is that the operator manuals are written as reference books, NOT tutorials. Even the so-called tutorials are horrible! It's like the people who write the instructions assume you already know how to use it so they make the instructions pretty miserable. Your best bet may be to find a friend who really knows how to use whatever GPS he/she has and see if they'll teach you the basics if you get one just like it. Then ALWAYS carry the manual with you in the field 'cause you never know when you might need toilet paper and that's about all most of 'em are good for.
