... the merits of the current production Keith Monks Omni or Classic over Loricraft?
The Loricraft is a cheap copy from the Monks. The Monks was and is a workhorse for professional users (Libraries, Radio Stations in the past ...) who wanted a reliable and perfect cleaning solution, be it 10 Records a day or 500, day in day out, week for week ...
The fluids are inside, the motor is powerful and very silent. It always was an expensive unit, in professional use that never was a problem because it was the way: Pay and forget.
Now in High End where most users clean probable 2-5 records a day or use those RCM mainly to remove dust from new records, the price is a serious factor.
