Yea, my AWS95 is one tone (somebody got it NIB that was sitting around unopened for ages, opened it up and kept it a year or two, then I got it). Most of my other 950's are somewhat discolored but not all of them. The front is plastic while the case body is painted, so you get color changes over time.
Wonder how much it goes for, are 950's as popular as IIfx and 840av's these days?
