The GPSMap 478 is the followup to the 276 series...which works quite nicely, both for automotive and marine use. The major difference is that the 478 has the BlueChart G2 coastal charts built in, which the older 276/376 did not. Also, the 478 can accept the XM weather radio receiver, which the 276 could not.
I've used the 376 as well as the 276, and the XM weather seems to work fairly well. The only possible complaint you may have is the size of the screen is rather small. If you don't have the need for the automotive use of the GPS, it might make more sense to go with the GPSMap 492, which is marine use only, and has a much larger screen. There is also a new unit coming out shortly, the GPSMap 440, which I believe will be replacing the 492.
The 492 is a good deal less expensive as well, going for about $600 retail, versus $950 retail for the 478.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
