I had a William Optics 80mm triplet. I didn't like it. It had bad coma (collimation wasn't even vaguely accurate thanks to crappy rotatable focuser poorly machined). Focuser lock didn't work, visual back was too large with only 2 screws meaning cameras would pivot slightly. 5 out of 10 mate.
It looked good though. It was better once I fixed it up myself but then I paid for someone else to do their job and they didn't.
