I had this in storage so I decided to look it up. I found people talking about how it was a really great controller, but I couldn't find anything in terms of pricing - with or without the box. 

I can't imagine its a high ticket item or anything, but it seems to be one of the higher desired controllers for getting a six button controller with turbo. I'm just trying to get an idea relative to a loose official Genesis controller. It seemed weird that I could find a lot of positive comments about this particular version of the competition pro controllers, but nothing else.
