I have used Keith Monks, Nitty Gritty, and VPI record cleaning machines going back to the '70s in the case of the KMAL. All are good for varying reasons. For lacquers, I prefer the Keith Monks because of its controlled area of suction. However, I find it too slow for vinyl or shellac discs. Then there is the thread feed. Perhaps that has been improved in recent years, but I cannot think of the Keith Monks without lamenting all the problems I've had with its thread feed.
