Zombo -
I agree with returning the unit you currently have. The Harbor Freight one - http://www.harborfreight.com/25-liter-ultrasonic-cleaner-95563.html - is far superior.
Looking at this link, there is a 25% off coupon. (Hmmm $85 minus 25% = $64.00) That is not a bad deal, especially if you live near a Harbot Freight store. Looks to me like there are five (5) in your area - http://www.harborfreight.com/storelocator/location/map
I found mine on sale, last summer, and after using the 25% off coupon (always available) I think I got mine for about $47.00. You might want to wait for a sale...
Good luck!!
I like mine as well other then the timer limit, I wish I could set it for a half hour or so for steeping. But when I bought mine my intent was to use it for cleaning my fired rifle and pistol brass for reloading and the timer fits that need just fine. It wasn't until after I had mine for some time I started to tinker with DIY juice and found this thread. If I was to buy one today it wouldn't be the HF unit, I'd get one with a longer timer. Some day I'm going to get inside mine and see if I can put a manual switch in and bypass the timer, then I can run it off a timer you plug into an outlet.
