I agree - while $4000 sounds a lot - I bet your saucepans are still serving you well after two or three fancy fridges have bitten the dust.
I think they still have the knives... but not sure if they are the same name - will check!... Was going to get them but forgot! Have emailed them and will possibly get them later! good to hear that someone else has these and they are still going strong!
Wusthof is a German brand of knives; I don't think they are related to your cooking system. They are excellent knives, although IMO overpriced locally (they cost half that in Germany when I got some, and that included VAT).
To be honest, for $4000, I'd pay a bit more and get a Combi-Steam oven; but then I already have a good set of pots and pans.
A tip for cleaning SS; Gumption works very well, as well as Barkeeps Friend, and at a fraction of the price.
