@RyX - I don't know how good the current one is. Mine is a Chicago Electric. It's actually heated, it turns out, and they don't tell you this. The problem is that it only runs in 3 minute cycles, and you need at least 4 minutes to properly degas the solution. (you have to run out most of the air bubbles so that the cavitation is small and dynamic enough to remove dirt). I also had to run new wires to the controls, because they're in the lid, rather than the base, and one+ wires broke. Network cable worked quite well.
In any case, the current one looks like it is about the same, power level wise, and has some sort of 'five settings' for cycles.
Keep in mind, these are _low power_ units. If you expect to throw shooting brass from ex-soviet ammunition into the box with a little bit of soap, and have them clean in 4 minutes, forget it. If you plan to toss in a razor with detergent and a surfactant (not the same thing, despite some of the stuff out there), and soak for a while, then vibrate loose old soap and dirt, it should work fine. Also, use _warm_ water - 115-150 degrees. It apparently makes the unit work better. Cold water doesn't. (I had always been told the other way around, until I started reading what the manufacturers of the BIG units had to say)
Edit - warning. I just saw people in reviews discussing using half full, rather than fully filling. Don't do that. The piezio unit can burn out if it's not spreading the vibrations completely. Also, the HF unit has a max 8 minute cycle. I'd prefer to see a 15 and 30 minute cycle, personally.
