Im leaning towards humminbird as my current dash is drilled for quick release. 718 worth a look comes with dual plus trans $195. I found 586c color for $244 with trans.
I have a humminbird 565 that seems to work great, on sale it's in the $150 range. It has the 60 degree transducer which is nice. Any of the higher end Humminbirds would be even better. I considered an Eagle Combo like CheapboatKev mentioned but I have a portable that works OK.
My buddy has a Humminbird 718. He really likes it. I have a 728. I forget what the difference was in features. Wasn't much. I think you'll like the 718...
