Replacement Parts Source?

Anyone know of a place to order replacement electronic parts? I need to replace one or more of the under dash electronic controler parts made by Denso.

I don't live anywhere near a dealer and the parts I need aren't stocked by average parts stores.

thanks,
A.

I bought a used EGR Valve from these guys in CA...... So far so good Ck Engine light fixed and it was less than half the cost of a new one!!! I would buy from them again for sure!!
