On the subject of Dishmasters
I found an Imperial Four model on eBay NIB with three different brush heads for cheap several months ago, so I nabbed it for a friend who lives in a 1960 apartment without a dishwasher. Installation was easy, but the relatively new stainless steel sink's deck had been compromised when it was installed, giving it a downward tilt toward the sink basins, and this made the Dishmaster sit even lower than normal, with the wings on the hot and cold handles hanging into the basins when opened. We tried fashioning shims but that presented its own issues. We gave up and put the old faucet back.
Incidentally, when Dave and I had a Dishmaster of our own (also an Imperial Four), purchased in the mid '80s, I recall the molded plastic/PVC deck mounting adapters raised it much higher than the current ones do. My friend might have been able to accept the tilting if the old style deck mount adapters were still available.
Shortly after this failed installation attempt, in the housewares section at a local retailer this friend found two dish brushes with handles that can be filled with a soap solution and dispensed with the push of a button. He got one for me and one for him. To me, this is a simple alternative to a DishMaster, which has become seriously overpriced. I use this dish brush on things that shouldn't be machine washed, and IMO it's an easily afforded "plug and play" alternative to a Dishmaster.
If anyone is interested in a Dishmaster, I'm willing to let mine go cheap. I may post in Shoppers Square before running an ad on CL or ND locally.
