I'm curious about ultrasonic myself, but nobody having a ultrasonic
cleaner has agreed to put in a plastic bag filled with etchant and board
and try. Couldn't even find someone agreeing to see if toner "resist"
survives ultrasonic in water.
As for the other motor/tray suggestions, i've graduated from tray to tank
some time back, and no wish to go back.
thanks anyway.

the round bubbler is still ok)
