My mother in law had one of these (well, a slightly older version with a flush control panel) and it was passed down to us and then we passed it to another family member who eventually ditched it when they moved to a place with a built in. Sort of wish I still had it- I've never seen cleaner dishes.
It always leaked a little bit out the top due to a bad gasket. I could have purchased a new gasket for about $95 back in 1990 or so but didn't want to spend the money on it.
We had a stackable washer/dryer so I plumbed the dishwasher in and left it in the spot next to the stackable. That way I didn't have to roll it in and out of our galley kitchen. My wife has never been big on doing the washing up, so the little room with the WD and the DW became known as "The Silverware Room", where dishes exit magically clean.
