Hello! I forget how fast posts move on this forum
I really don't have a wide amount experience with the current crop of residential front loaders, to reccomend one over the other. Speed Queen makes one I know intimately, and, from its example, and what I've seen of the others, they all seem to be scaled down versions of industrial washers. I would go with information on places such as the aformentioned Consumer Reports, or direct info from people like Dan!

I have been seeing both Neptunes and the Sears model in a few places for doing small runs, and nothing but positive responses on both.
Now, about the laundry chemincals a bit more. I do mean you need to scale back on all chemicals, not just detergent. And yes, you can use any off the shelf detergent in this type of washer, you just need to lessen the amount. Because of the type of dispenser used, liquids do work better, but as long as you break up a tab, I see no reason it won't work either, just don't stick a whole one in the dispenser. A good visual gauge would be that you have just a small amount of foam on the surface in the first wash of the cycle. If the cylinder is filling up with foam or it's beginning to look like an old rerun of I Love Lucy, you've got too much soap

As an example, the 60 pound load industrial washer I pictured above uses about 3-4 ounces of industrial soap for a full load. They have specific machines that look a lot like the devices used in hospitals to meter drug injection that are, and have to be extremely accurate, to guarantee consistancy thru a day of wash loads. The level of technology in all the washers mentioned in this thread are just amazing to me.
Oh, and as a sense of scale, the washer I pictured costs about $8,000 dropped at your door
