I just received my CD1w ultrasonic cleaner from Shining Image - ebay, $39.65 with shipping. It cleaned a super adjustable very nicely in 2 ea. 3 minute cycles. Also did a fine job on a Schick Krona and a Red tip at the same time, again 2x3minutes. On the box it says it is a CD7810A model. There are at least 3 more on the site now. So far, it looks like a keeper. It passed the aluminum foil test with flying colors. I used about tablespoon of Dawn dish soap.
