The diyaudio.com thread on ultrasonic machines suggests that these machines involve more than $500 in parts. And this "parts cost" calculation is always problematic since it fails to take into account so much, including rent, engineering, design, prototyping, salaries, shipping, etc.
That said, yes I think ultrasonic cleaners with the features of this or the Audio Desk would sell like hotcakes at a $2000 or below price point.
