just put this one in my friends nautique, sounds greeat, and it hardly ever skips, not much more then price wise then yours. it looks like it puts out 10 more watts to each channel, but it does not have the ipod connector from the back (usb). but the aux in the front works just fine for us. i think it would be worth the extra 30 bucks, clarion makes a good product.
