VHF/Hailer/Fog Horn Suggestions

I'm getting ready to start my trip to Newfoundland/Nova Scotia.  I keep 
thinking that it would be really nice to have a hailer with a built in fog

horn.  I've been off researching them and it appears that for the cost, I 
may as well just get a new VHF which incor****ates all of the features into

one unit and that is remotely controlable from the remote mic in the 
cockpit.

I've been an Icom user all along, and am tempted to get the IC-M604, which

is basically the same form-factor as my current IC-M402.  The thing that 
really pisses me off is that the cables for the remote mic are different 
than what I have in there now and it's a royal PIA to remove the old ones 
and pull new ones.  As a result I'm looking at different vendors.

I've always liked Standard Horizon and their model GX2360S seems to have 
all of the functionality that I like at a better price ($295 vs $420).

Does anyone have any feedback on these units or suggestions for others? 
How about the actual horn unit?

Also, I'll need a guard for the horn.  Here's a picture that I have for
the 
foredeck light.  Does anyone know where I can find these?
