Advise sought on equipping A Baron

Greetings,

I'm buying a 2011 Baron GS, 300 Verado, 9.9 long shaft kicker. I am looking for advise & opinions on chart plotters Marine radios and fish finders. All input is appreciated. I'm taking delivery in the Spring of 2011 so I have PLENTY of time to decide. For folks who have dual set ups - Do you like them? I would consider a dual GPS/fishfinder but am leaning more towards separate units. Also, any advise on mounting is appreciated. If you mounted you electronics a special way and like it, let me know. If you have any "If i had to do it over I'd change XYZ" comments.. I'd appreciate those too. Pics of your set-ups are even better. Budget isn't really an issue but I'd rather not spend thousands when comparable set ups are only hundreds.

Thanks,

Steve
