I recently picked up a black sports edition dreamcast. It's complete with all the hookups and includes the black DC controller.
The date on the bottom says August 2000. I tried a few games on it, and all play fine.
I'm not sure if I want to jump into DC collecting (I already have the regular DC system with a few controllers, etc.) so was wondering what this thing is worth. Is it worth more than the regular system? What is a good price to sell this at?
