If my memory serves me right , I had a trade offer made by him (her?) several months ago (back around may I think) for one of my 360 controllers. Deal never ended up going through , partly because of poor communication (responded very slowly to my pm's) and partly cause they kept trying to talk me down on the price , which I wouldn't budge on. I think my feedback also kept them away (it wasn't as high then as it is now , but it was probably in the 40s at least).
Granted this really has nothing to do with the case at hand , but I just felt like adding in some of my personal experience with them.
