Bradshaw International, GoodCook Microwave Plates, 4 plates

They really do seem sturdy and surprisingly lightweight. In the few impromptu tests I've conducted so far while pulling food out of the microwave, these really have stayed much cooler than our other plates, including some Corelle. Even right under fatty food, they have stayed cool enough to hold. Also, they have that handy little tab on the side, so that you have a place to grab, even if you did manage to get them too hot to handle. When I was shopping, I couldn't find any dimensions, just that the size was "standard." I'm a guy, so that didn't mean much to me. Anyway, they're roughly 10" in diameter with a lip of nearly an inch. The flat part of the bottom is a little over 8 1/2 inches. These are listed as dishwasher safe, and at least so far, there have been no problems, even on the lower rack. I saw some comments elsewhere that repeated exposure to the heat in dishwashers will likely cause some degradation in the plastic over time resulting in cracking and brittleness. However, the articles also admitted that "over time" meant maybe 15-20 years. I decided to chance it. Recommend.
