WOW! You know my Dad raised us with some pretty high ethics and firm morals that have served me well, but all of a sudden I find out he's involved in GPS-GATE!
This GPS-GATE has something to do with sex and ants, backwards compatibility, serial dongles and all sorts of coded messages regarding r232!
Next thing you know I'll discover he was at Woodstock or something!
Be aware, you need Linux, Perl Perl/Gtk to run it. I've always hoped to see a group of collaborators develop, but so far no others have expressed any interest. I just used it yesterday to navigate the shoals along the east shore of Lake Winnebago.
Someone led me to an online magazine called MadMariner.com which has a whole series of articles on PC based GPS and software reviews. There is a free 30 day registration period and it is an interesting site.
I learned quite a bit there. For those who just want the bottom line, their consensus is kind of "you get what you pay for". Best $0-100 is SeaClear II (free), Best $100-300 is Tiki Navigator($148), Best $300-1000 is Coastal Explorer ($499). Just their opinion and there were lots of close seconds.
