Canon 1Ds and 1DMK2: Worth Selling?

Hey folks -

Before posting something in the "For Sale" section, I wanted to get a feel for whether it would even be worth my time.  I have an old Canon 1Ds and 1DMk2, both bought new when they were released.  That makes them almost 11 and 10 years old respectively.

Is it even worth it for me to try and sell them?  Would I get anything for them?  At this point, Canon's service people won't touch them if something breaks: "Sorry, we don't have spare parts in case we break something." That was their response to me when I asked them to clean the sensors for me.

Thoughts?
