I know most of the posts here are for high-end appliances but I had to tell you about my new microwave. I am amazed. It is an inverter microwave from Panasonic. I don't have any connection to Panasonic but this thing is great. I can actually cook in it. If I set it to 50% power I get real, honest 50% power the whole time. Makes it so much easier to steam delicate foods or cook touchy items like fish.
It appears Panasonic makes most of the inverter units although they may appear under a different name sometimes. Costco is the place to go - they have the very best prices. 5 stars.
