Some one did this - but I don't remember who it was.

There's a whole thread about doing this! With elaborate how-to instructions and photos. I'm considering the same thing. The European-style Monogram door is reasonably compatible appearance-wise with the Cafe line (though the handle is thinner), and the whole door can be swapped onto the substantially less expensive Profile Advantium, and is amazingly inexpensive as a part (the complete door assembly can be had for well under $100). The "pro-style" door protrudes more from the body of the oven than the other two styles, though the handle is nicer and even more like the Cafe handle. Don't know if the handles are interchangable if you keep the doors, or for that matter if a handle from a 30"w electric Cafe wall oven will fit on an Advantium door.

Thank you!
