So, one of my pitot tubes is incorrectly mounted. It has the drain hole on the top, so has been installed wrongly (a left side one mounted on right side). I literally had a nervous breakdown when I got the quote for a new one: $11,137.29!!!!! I mean, are these people insane?

A used one they found was still $3-4K, which is total madness. How can a used pitot tube be almost $4K? I mean, these are standard parts and parts numbers, no? Probably shared by multiple aircraft. What is going on?
