Assuming it completes a set, what is the most you would pay for one lego piece (non-minifigure)?

I was thinking about Bricklinking a 10179 at one point, and if you don't know, the Lattice pieces in the back cost about $320 for ONE PIECE of Lego. What do you think? What is the most you would pay for one piece to complete a set? I would just use a substitute. Assuming it didn't make a huge difference, I would spend maybe $20 on one piece before I went elsewhere. What about you all?
