OK, it's months late, but I had one of the first Coulter 13.1" ers, big, blue and boxy. I built a shed for it in my back yard and drove it to Blue Canyon for observing. It was $400, a terrific bargain. I did not have many eyepieces at the time. As I recall, images were ok, but it was a bear to use. I sold a 6" reflector on a pier for $200 to help pay for it, as I was a poor grad student at the time.
