I guess I should have phrased this more as a two part question: is it true Sharp makes all these microwaves? And therefore can I assume that the bad rap Viking gets, doesn't hold true for their microwaves? Any info about Viking warming drawers? They happen to make one that will fit in my old Thermador spot, and accepts a wood panel front which I want...

Maybe I should have titled it "Viking microwave" ...might have gotten more response?
ordered the Viking Micro today, guess I'm on my own on this one ;)

I read your post this morning and meant to answer. As I understand it, Sharp has the monopoly on making microwaves in the US (however Panasonic may make their own). Anyway, I believe KA, Viking, Jenn Air microwaves are just " rebranded" Sharps in their own exterior finish/design.

Here's what an appliance expert says on this matter:

The Best Microwave Drawers (Ratings/Reviews)

By the way, Viking appliances (rebranded Kitchen Aid interiors) do indeed have a nice finish.

Here is a link that might be useful: Microwaves:

I thought the Viking was made by Whirlpool, but I haven't looked that closely at them.

OP-my post applies to microwave drawers.
