Doesn't have the dual-action agitator...
...and it has dumbed down water level control.
I don't think that the water level control is just two settings. I suspect that fill can be anything between small and large. I played with the control and turning it there is incremental resistance to indicate different water level settings, or so it seems. I din't read the manual. The machine may actually have more options than what is apparent from the control panel at first glance.
I've never seen commercial Maytags with a dual-action agitator.
Crazy expensive for you guys is often regular pricing for us. In this case one is supposedly paying for the heavy duty, commercial-built quality. These are the same units that are found in laundromats, residential care places and other businesses. Anything that's earmarked as 'commercial quality' and intended for business use is usually priced much higher than stuff made for home use.
If I purchased these units from another distributor and not Costco, I'd probably have to pay even more. As a business I'd be able to recoup part of the purchase price and depreciation via my tax return.
