My question would be if you are not going to get the good maps to go with it, then there are several units that are just as accurate and a couple hundred cheaper. That said, please don't think I am bashing the 176. It is on my purchase listfor the very near future.
What will I add on? First for me will be Metroguide USA. Then Bluecharts, then Fishing Hotspots.
If you can't decide which add on maps to get, then goto
http://www.garmin.com/cartography/mapSource/. You can zoom in on your area and see what kind of detail is available in the different mapsource products. [img]/infopop/emoticons/icon_cool.gif[/img]
The only thing that is not available at that URL is the Bluecharts. From what I have heard they are electronic versions of the paper charts and very high quality.
