I have a Garmin ETrex Legend. I love the little thing. It has mapping, 8MB of storage (enough for all of SE Texas at street level). This comes in very handy when navigating unfamiliar waters. Major aides to navigation are included. The screen is a little small, but that is solved by a feature that lets you make the numbers LARGE. The menu system takes a little getting used to, but after that it's a piece of cake. The only thing it doesn't have that I wanted is tidal forecasts. All this for less than $250.
