It appears GE is the only appliance manufacturer that still offers 27" wide drop-in style ranges. After purchasing an older home, I discovered that the current range was nearly forty years old... and atrocious. My choice was simple... either find a new 27" drop-in style range to fit in place of the old, or spend thousands of dollars restructuring the lower cabinets and countertops to accommodate a 30" "standard" range.
As far as I was able to determine, GE is the only remaining manufacturer that still offers a 27" drop-in range. Thanks, GE, for saving my kitchen with this updated version of a drop-in stove.
