I bought a new 1969 6" f/8 Optical Craftsmen using most of my savings when I was in high school. I wish I still had it. To my then 16-year old eyes, the views were comparable to a 6" Cave that another member of my astronomy club had.
I did side by each imaging tests between my 8" f/6 Springfield (optics from an OC Discoverer), an 8" f/6 OC Discoverer OTA, an 8" f/6 OC Connoisseur, and a Cave 8" f/7 Lightweight Deluxe. At the time, I thought that the Cave was a microtad better than the OCs, but in retrospect there probably really wasn't much difference between them. The OC OTA seemed to be poor, until I discovered that the mirror clip screws were too long and pinching the primary. After I corrected that, it takes very nice images. I still have that OTA and the Springfield. Sold the Connoisseur and the Cave.
ETA: I compared the Discoverer before I took the optics out of it and put them in the springfield, with a Meade 826 (with Coulter optics) I had on loan while working at Meade. The OC beat its pants off by quite a margin.
