Dave,
I found mine on ebay. This is their direct email.
supplystuff@gmail.com. I paid $9.xx a piece for 3 2600W elements for my oven and I bought my fan motor, fan and a three speed switch, all for just over $110. Talk to Jose', he seems really knowledgable and is very helpfull.
Regards,
Glen Porter
