The first one is an EXCELLENT beginners imaging scope-- looks like the mount is an Sirius EQ-G this is the setup I usually recommend to a beginner imager. The only upgrade here would be to the Atlas EQ-G which is heavier duty than the Sirius mount. But this is still a very good "rig" for imaging. (limited aperture for visual)

The 3rd one is excellent for visual with 10 inches of aperture and GOTO. You need to decide what you want to do? My vote would be the 10 inch as it would show you many many great visual views of the night sky.

Good luck, and clear skies.
