Abomb,
Well, I got a good price because, as I said earlier, I got the B&W (noncolor) version. They have two or three noncolor versions of the same finder, with gps (m52 S/GPS, M56 S/MAP, and probably some others. They are essentially a non-color version of the x67/m68 models, and it was a special purchase by Cabelas. I got the m52 S/GPS model (the m56 S/MAP model has a basemap of us waters built-in. The one I am getting doesn't have the map, but records and finds waypoints. I figure I don't need the mapping, since I really just want to mark where I catch fish, etc... I don't need a digital map to know I'm in the middle of a lake.
It helped that I bought a bunch of stuff at cabelas during a grand opening awhile back and got a $25 rebate cash card to spend in the future, and also got a $20 preferred customer rebate. Their price for the unit was $150, so I bought it with the rebate cards - $105. I call that a deal. I'm not sure how visible the single-color display will be in bright light, but it's got the same operating temperature range as specified for the X67, and the same set of sonar features + the gps. I think I'm really going to like it. I wanted to use it in my boat during spring/summer as well, and like the idea of having real-time flasher and chart recording for all-around flexibility.
I hope it works as well as I imagine it will.
