Summary: Our 10+ year old Sharp bit the dust so I looked at the Panasonic Inverter Microwave. Paid a little more than the other basic models ($100-$125) but after using it for a few weeks, well worth it.
The sensor button is great. You don't have to guess, is it 35 seconds or 54 seconds? Food comes out hot every time! Pay attention to the popcorn button. You have to get the size of the bag correct or results will suffer.
Turbo defrost is another great function.
Summary: Microwave works great except for the terrible front panel display. If, like me, you install the unit on a counter top and want to be able to read the display, you had better be under 5 feet tall. Unreadable unless you stoop down...
Summary: I bought this model at Wal-mart, and came to Amazon to check for price comparison (Looking for microwave as a christmas present). I've been very happy with purchase. Microwave looks very nice, I have mine sitting on a stand. Nice features, large capacity, powerful, quiet, and heats very quickly/evenly. Would definitley recommend this product based on the performance of the one I purchased. Amazon plus-10 or 15 dollars cheaper than what I paid.
Summary: We LOVE this microwave oven. It is small enough to fit in the boxed space in our cabinetry provided by the cabinet people. It is the exact size for the space. Not only that, but this microwave heats lightning fast! Normally putting soup in the microwave we had to heat it for about 4 or 5 minutes for it to be hot. Now it takes about 2 minutes. 1300 watts is a big difference. The price was right. I did a lot of research on microwaves.
Summary: We bought this model at Target and tonight it died in the middle of warming dinner. We liked the features on this microwave very much. We purchased this microwave within the past 12 months. So be warned that it doesn't have a long life. There are other reviews on Target's website that I read tonight that they also had the same short life as our's did.
