The instrumentation on my boat is close to "packing it in". It's comprised of Signet wind/depth/speed, a Furuno 1621 radar (which only works intermittently) and an ST-4000 autohelm none of which is connected to anything else. They're each just separate free-standing instruments. There's not even wind input for the Auto Pilot and therefore it can't be used to maintain a wind relative course.I'm seriously considering putting together a whole system based on Raymarine's E-80, ST-60 instruments, the 125 GPS and an 18" radome radar with maybe a fish-finder GSM-300.It seems like (after much web based and in store research) Raymarine has the only system capable of integrating all this data. However, I'd really like to see it all playing together to try and evaluate the usefullness of all this and the readability and "see ability" of the display. Is there any place I can see a real demo of all this stuff? I'm not looking for something as elaborate as a sail on a real boat. I'd even settle for a decent video based demo (however a real "hands on" demo would be best). I just can't seem to get a handle on where I might see this. Begin Rant: It seems that a company like Raymarine would put some kind of useful demo together to induce people to spend this kind of money. End Rant.Short of a demo, opinions and observations from anyone who has such a system (and really uses it) would be most welcome. Please, either email or post whatever opinions and impressions you have.Thanks,-Smitty
