How to find discontinued Dacor oven part?

Thanks. I wander why Dacor have the part #82810 listed but do not carry it.
I did look for the switch board "verywhere I could thik of, both by phone and Internet, including Dacor and their autorized service and parts providers, but always got the same answear: "The Part is discontinued and don't know where to find it".
I found a company that remanufactures oven control/switch boards, but they want my board. I don't want to send it to them, in case something happens to it, I have nothing.
Would not mind buying the part used or remanufactured as long as they don't want my part before I try theirs.
