I bought a degritter a couple of weeks ago. Prior to that, I was using an old nitty gritty I bought used on agon. I was happy with it but kept reading about the ultrasonic machines being so much better. However I couldn’t get past all the problems people had with them plus the cost just seemed crazy and hard to justify. Finally COVID craziness got to me and I broke down to buy one. Apparently they are in very high demand and many dealers sell out quickly. I will have to say with my brief experience I am very happy with the purchase. Most of my records are very clean so wasn’t sure if it would make that much a difference. But now I would highly recommend the machine before upgrading any of your equipment. It really makes a difference even on records you think are in perfect condition.
