I also bought a Garmin 76S and find it a pleasure to use. The 25meg memory capacity comes in handy for multiple use functions. Besides sailing and driving, I also go hiking. The ability to store so much data for both land and sea is impressive. Even if only used for navigaton, it has a built-in barometer that can be used for weather prediction. Also, it has a built-in tide chart. Best of all, I got it on ebay (new) for far less than the retail price.
