Any thoughts about a decent ultrasonic for small business use? It doesn't need to look good for customers and it doesn't need to be the most powerful on the market, but it does need to reliable and strong enough for thorough cleaning of finished jewelry. Thanks for any suggestions!

I have an "Elma" unit, neat and compact, variety of ultrasonic programmes, timer, heater (rarely used since I have standardised on a fluid containing ammonia). One problem, it did not come with a holder for beakers, but it was the work of an hour or so to make one out of a sheet of Perspex. I have regularly run it for 8 or 9 hours when doing big orders with no problem at all. Might suit you, check them out.
