New Microwave Oven Needed!

H has been coming home late from work lately. Being the good wife that I am, I usually keep some dinner for him. But by the time he comes home, the food is all cold and not so palatable. I usually heat the food up in the microwave oven. However, when I tried to heat up the food yesterday, the oven seems to "smell funny"....not exactly a burnt smell but just weird. In addition to that, the food seems to be taking longer to be heated up. I supposed this old unit is destined to the junk yard, and it is high time I get a new one. Wonder if there is a sale where I can get one with a convection function as well.
