Who said any thing about Furuno????
You are always going to get the latest is greatest crowd mate, that's the way it is these days...
Before Furuno it was Garmin before that it was Furuno again, Raymarine were in there some where too.... It is all about marketing...
Any way back to your original question.....
Get the biggest screen you can afford with the highest powered RMS transducer. Both elements are crucial when looking for fish. You also need to be happy with the menu structure, a mate of mine has a popular brand that takes way to many button presses to get between the most used pages..
Good luck with it.....
