Some of us started up a discussion about this ultrasonic cleaner off-topic in another thread so I thought I would move the discussion here. I have used an Okki Nokki for the last 8 years, but have the opportunity to buy my dealer's Audio Desk at a steep discount. A new one with some revisions is on the way, so my dealer is clearing out their ex-demo. After evaluating it at home all weekend I've decided to buy it. I am very pleased with results so, especially on some crusty old records I have, like the Liberty/Blue Note copy of Chick Corea's Song of Singing shown in the picture below. I plan to keep the Okki Nokki, and will use that as a pre-soak machine for heavily soiled records and used records I buy on eBay, Discogs, etc. How many other users out there? Maybe we can use this thread to share experience, tips, etc.
