What are an X55 and Combat pedals worth?

[Thud20]

I got a package with NewEgg on a TM Warthog that included the pedals for around $420. The rebate required buying the combat pedals that I already have. What is a fair price for the X55 and combat pedals I currently own? They are less than 3 months old and I paid ~$375 for them. I had to send the X55 back twice to get the perfectly functioning one I have now. I can fly the X55 like playing an instrument where you think what you want done and your fingers do it. I hope I can get to the same level with the TM Hog stick. I want to put it on CL or Ebay.

OK, I've decided to sell them for $250, it's a fair price for brand new pedals and a few month old X55.
