would like your opinion on a medium to larger studio setting. ive tried elma but had alot of issues with it…
I used L&R ultrasonic cleaners for first 20years, and a CREST model 275 HTA for the last 20 years. My conclusion is both brands cleaned well but the L&R required repairs along the way . The CREST has been PROBLEM FREE for 20yrs. I go with CREST.
thank you so much for the recommendation 
sometimes it does take one to actually use it and tell which ones good and not. cannot just rely on what the companies say about their product…
it would be nice if others can also give some suggestions and inputs on this topic
