Hello, I sold my RS550's, but I still have the risers left for sale. They are in excellent condition except for one small chip on the back side of the base of one of the risers. The chip is about 1/8" x 1/4" and is barely noticable. I would prefer paypal payment, and I'll get the risers shipped out immediately. Feel free to email me at [email protected] with any questions. Thanks! David PS My user name on ebay is perrypoke and I have nearly 200 positive feedbacks, just so you know.
