Yea I got the one from costco too, I think that's the best price for this size screen. I actually mount the screen it at the back on the passenger side c-pillar, near the rear window. Since I need to turn my head back when I back up anyways, so I can see both rear windows and the screen at the same time. Also I can hook up both screen and camera from the back up light power. and can get excellent signal from the wireless camera as they are so close.
