I have used Raymarine on the current boat and the last boat. I have found that customer service is helpful with the few problems I have had. The current boat has an E80, E120, St 60 wind, depth, multi and speed, weather, pilot and an ST70 multi. In 10000 miles of sailing we did loose a Pilot course computer and ram (suspected lightning) but the company has been awesome in helping wiith troubleshooting and advice. I'd buy Raymarine again.
