We stumbled on this website last week by accident but what an incredible gem to find! Compact Appliance is an online appliance seller [duh] which specializes in countertop and small space appliances. Pictured here is a EdgeStar Deluxe Portable Countertop Dishwasher $185 which has the capacity to fit up to four standard place settings
as described on the site as: The EdgeStar Portable Countertop Dishwasher (DWP40S) has the capacity to fit up to four standard place settings with the convenience of operating right on your countertop - saving more water than you would if you were to wash the dishes by hand and with no permanent installation, and more energy and space than with most other dishwashers. At 18 1/2" high, the DWP40S EdgeStar countertop dishwasher is low enough to fit under most cabinets, and the included quick connect faucet adapter makes hookup to almost any faucet simple. A five foot hose is included.
