HAving used the 16.5 in my LP store for 13years it never missed a beat and I would clean 100's of LPs a week. The thing I liked about the 16.5 was that you could monitor the application of the liquid and brushing as a manual exercise as opposed to the automated 17 which did not appeal to me. Noise is only a temporary issue as an LP will take 30secs to a min to do. As they go for 350-450 on Agon, it is a very wise investment IMHO.
