Can Anyone Recommend a Good GPS?

[nachoman]

I used a rather sophisticated GPS and computer system for my last job. Of course, we were out in the middle of nowhere traveling on roads that were almost less primitive than dirt roads . But, my experience is we were often better off navigating by dead reckoning. I've never tried using one in a city, though. The small all-in-one type units available today should work pretty well as long as you use the maps and imagery that they are designed to work with.
