Here is an excellent condition Okki Nokki RCM with Dust Cover and the Walker Prelude Quartet Cleaning Kit. The RCM is in perfect working condition. The only reason for parting with it is that I upgraded to much more expensive ultrasonic cleaner. It retailed for $649 with the cover. The Walker System is a 4 step system with an active enzyme cleaner, pre-mixed cleaner, ultra pure water, and a high resolution rinse. The kit retails for $215. All 3 fluids, enzyme powder with mixing bottle, 64oz water refill, 4 separate brushes, and instructions are included. Please see the pictures for the levels of the fluids. The ultra-pure water and refill jug are completely full with lab-grade water. Local SF Bay Area pick-up/delivery only.
