Price Check: Used M030 Sway Bars?

[78F350]

I'm trying to determine a fair price for a pair of M030 sway bars with bushings. I can't find any 'solds' of the right part number for a good reference.

I found new ones at a few places for about $300 rear and $400 front, and that's way higher than I expect a used set should go for.

Here's pics:



This set appears to be for the base model with 24mm front bar and 19.6 mm diameter rear. I do have another set with the 19 mm rear for the 'S'. Would there be a price difference?
