I wish I lived in Australia, there is only one place in my area that works
in microwave ovens, most people just toss their's and get another one, very
little money is to be had repairing microwaves in the States, many appliance
and repair places have shut down over the years, the place that does repair
microwaves won't even let me get TV flybacks from them, I guess money is so
tight they have to hold on to what they got, which is the way it is in alot
of places around here.=/
