Western Super-X sales display value

I noticed this sample set with sections recently on Ebay. Is this sort of set usually worth the $113.00 that the auction ended up closing for? (scroll down after link opens):

Based on the auction we know that one person thought it was worth $113, and someone else thought it was not worth that much.

Probably a whole lot of people thought it was worth a lot less. My guess would be that a fair retail price would be more like $50-75.

Matt, you probably already noticed this, but cartridges no. 5 and 11 are evidently replacements.
