^Should be worth anywhere from $35-45 depending on condition. There was an abundant amount of these available for $50 NIB (still might be available) from an online retailer maybe 4-5 months ago.
Personally, I think it's worth more but just like you said, there is a good amount of them out there. I sold mine for about $70, which was virtually NIB, wrapped in white carbon fiber vinyl and came with an additional clear case like 3 months ago =/
