I have an OBrien kneeboard that I want to sell. I've never used it, Jeff got it over a year ago for free from his ex boss because she was just going to toss it out. It's been used but it's in great condition (like new). I went online and looked at OBrien kneeboards and they go from $75-$250. What's a reasonable price to ask for this one I have?
Here are two pics.
