Owners like this Frigidaire Professional 1769865 column set at about 1/3rd the price ($6000) of Thermador. Huge, though, at 66" wide.

I have had my Fridgedaire columns with built in kit for 16 yrs I actually run a catering biz from my home Not one issue in all thta time and even now they are still IMO best bang for your buck. I have used the columns separately with their own builtin kit where the width of the 2 together was a no go we put the freezer column in a pantry and thta worked.
