I have a 930 Record bought in early 80’s. Bought a 770QE in 2016. I had taken the 930 in for an oil change when i got the 770 and had not used it since. Last month during mask production i uncovered the 930 and she just took off. I was so happy. No noise, no caught threads. Absolutely ran like a dream. And so quiet! I love that machine and will not part with it! I think it is the best purchase i have ever made!!!
