Good choice! I completely agree with your conclusions. May I make the following suggestions, based on my experience?
1. Make sure that there is enough space for the ultrasonic wave to develop. That means spacing between the tank and the record, and record to record, must exceed 1.5 inches at all points, even when records are warped (assumes a 40KHz machine operating at full frequency spec).
2. Keep your cleaning chemistry between 40 and 50 C.
3. Finish by rinsing off the cleaning chemistry.
When I failed to do one or more of the above, records came out looking clean, but further cleaning revealed that much more gunk had been left behind. Had to re-clean 2000 records, which I do not recommend.
Enjoy!
