There's been some posts re microwaves, and people have replaced their microwaves with standard "home use" microwaves without any problem. I would probably try to go that way since microwaves are so cheap. Just a suggestion...I bought a Panasonic microwave for use in our cottage and it was a heck of a microwave. Panasonic uses a special magnatron that enables it to run continuously with out the normal on off on off cycle typically found in microwaves. As a result, the defrost cycle was better than I've seen in any other microwave.
