Have em.
I bought a set of these back in 96. Awesome and still running at my cousin's place. The only thing I didn't like about them was the water level control. It is a five position selector, but only a three postion pressure switch. The lowest, middle, and upper levels are positive control by the pressure switch. The other 2, medium-low and medium-high are determined by time.
The machine times how long it takes to fill to position one and then uses time to roughly esitmate the next level up. Works okay if you are running cold/cold or warm/warm. But the cold rinse could be trown off my a warm wash estimate.
Other than that, I liked them.
