Ahoy Dick,

I was having the same problem, decisions decisions, decisions. I
happened upon Rosepoint software. Strange, the Rosepoint Coastal
Explorer is almost identical to the Maptec Offshore Navigator Pro.
The real neat thing is it is about $200.00 cheaper. I went to this
site
http://store.milltechmarine.com/index.html and they have a package
that contains the Costal Navigator and an AIS reciever fot the price
of the Offshore Navigator.

I bought it and am happy with it.
