We have been using a raymarine chart plotter (C) for over 10 years and have 2 E80s, a raydome radar unit, DSM depth, ST 60s and SR 100 Serius weather that we've been using for about 4 years with no problems at all. And it's idiot proof to install and operate once you get the hang of it. Their R&D use to be second to none but I do not like the fact that simple extension caples and etc.. are way too $$$. We looked at the Garman touch screens before selecting the E80s and in hind-sight, after everything is installed, Garmen would have been more reasonable. Like I noted, it was the little things like networking the Seatalk cabling, extension cables yadda that added up fast. Their list prices are crazy on their units (even with boat show prices or rebates) so we never paid full retail and purchsed on line. In summary, we've been very pleased with the product and their customer support that spends time on the phone with you..vs email.
