I actually found the empty microwave in st ives, so I don't think it was 
one of yours. maybe theres a coiler somewhere near here ... :D ANyway, as 
luck would have it, i found an old microwave thrown out today! yay! I took 
it home and grabbed the transformer :D Now I just need to find 5 others. 
(the extra 1 coz I want to make a UPS for my computer. I bought the car 
battery for that today from kmart for 30 dollars. Thanks for the offer btw, 
but now ive been given hope again! maybe ill find a few more in months to 
come :D
