Some here would say that the KD-23 machines offer the best of both worlds:  They still maintain most of Hobart's build quality, but they are the first KA dishwashers to employ the improved Whirlpool "power module" pump system.

The styling of the Architect control panel differs from the other series 23 machines, but mechanically they're the same.  There seems to be a love-it-or-hate-it opinion on the Architect styling, which was intended to have the panel blend in better with cabinet drawers that might be adjacent to it.

As long as it's reasonably priced, like $100 or less, in proper working order, and you like the look of the machine, I'd say go for it.
