If you handle records properly and remove the dust with a carbon fiber brush properly before each play, the need for a RCM seems to be greatly reduced. I guess if you buy a lot of used records that are very dirty, it could come in handy. How does grime get in there without fingerprints? Records are only exposed while playing,Then immediately put into MFSL rice paper sleeves.
I tried a RCM a while back (forget what type-around $700) on my oldest records (although they were in very good shape) and could not tell the difference after they were cleaned, playing them immediately before and after.
I remember a long time ago an engineer who ran a high end audio shop told me not to put any liquid on a record - just use a carbon fiber brush and it has worked for me for 40+ years.
