The biggest thing with my 927 was taking the motor apart and cleaning and lubing. The motor was a little noisy when I first got the turntable. After it was restored it was very quite.
I didn’t even need to repaint mine. The enamel paint was so thick it would take a hammer swing to mar it. It was soiled, as was the entire turntable. The platter bearing is huge, and was perfect. My bearing was oil based, but I have heard that some are also grease fitted. (Like Garrard).
Mine is in very good shape cosmetically. I would rate it an 8 out of 10. It has a suspension frame too. I want to do a good cleaning, dismantle the motor to clean and lube and then install the new motor mounts. I have a local tech who will most likely handle the powersupply electronics replacing caps etc...
