The Kitchen-Aid is too new to have a Partycycle! I have a KDS-58C that had been partially converted as a built-in but it still has it's cabinet and cord winder. The upper rack was in bad shape and I was looking to get a replacement for it at a thrift store when I saw this KDS-18C with very nice racks. This one also still has the original constant-rinse while it was replaced with the newer type on the KDS- 58C. As for the Frigidaire, I have almost kinds of Frigidaire dishwashers, I have 3 of the newer Super Surge models that I really like too (one with the rapid advance timer, fan drying, auxiliary spray arm, double detergent dispenser and 150 degrees wash) but the beautiful porcelain in the older Spay Tube machines is so nice! And that sound they make. I just love these machines!
Now, the only Frigidaire dishwasher that I'd really like to find is one of the Canadian portable models that rides on an air cushion! These dishwashers didn't have casters. Instead, they had a built-in air pump and a "Ride Aire" pad under them. Frigidaire Canada innovated in 1965 with the Ride-Aire system on it's refrigerators but in 1966, it became available on portable dishwashers and there were even some Rollermatic washers made for Habitat67 that had that feature! As far as I know, in the system was also used in the US but only on refrigerators and starting in 1966.
