Wish my truck was working, but I'm going to check into it. I love those machines. Why do you call them 1 arm wonders? Don't they have a power-shower sort of thing on the top of the tub? Or did that only come later?

Sorry but I really don't consider the constant rinse to be all that helpful in certain situations.  1-arm wonder, because there's only 1 wash arm and that's under the bottom rack.  Nothing for the upper rack that's separate.  Put a whole bunch of big mixing bowls, a dutch oven or two and a couple of other things in the b0ottom rack and you ain't gonna get much cleaning in the top rack cuz the water's blocked pretty well.  Not my cup of tea when I'm power baking and cooking. 

You know, I'm so used to running multiple loads, back to back at work that doing the same thing at home just isn't that big a deal to me so not every load has to be a Bob Load@ (ducks and walks away quickly). The most important thing for me is that a dishwasher has a quick cycle and a cancel/drain button so I can expedite the loads.

The racking in the pre-second wash arm KitchenAid dishwashers, to me, was perfection. By that I don't mean that it was either the best out there, nor the most capacious, but for old-fart users that washed DISHES, like with Maytag, everything was based on "the circle in the square". Large plates down the center where the upper rack was shallowest, small cups in that shallow part of the upper rack, etc,. etc. By the way, I will also tell you that when we bought our first KitchenAid KDC-17a back in 1974, I noticed right away that it couldn't hold as much as the GE SU-70. If you knew what you were doing, that machine held a sh*t-load because there were so many tricks to loading it correctly and effectively.
