Hi Melody - my microwave used to interfere with my cell phone! Had to get enough distance between them...
Thats the only cooking appliance I ever use (living on Ensure has its pluses! But I do use the microwave to heat broth once in a while) - microwaves are very inexpensive these days..... and I think much cheaper in the long run to use then the stove etc. for appropriate items..... try any of the eletronic store sites, and I think also stores like Sears etc. will match any price out there......
