I bought a Sansamp RBI from Soundoholic. He answered my pm's VERY quickly and he sent out my preamp as soon as he got my money. The transaction went very smoothly, but when my preamp got to me there was no power cord. PM'd him and he was very apologetic and got it sent first class to me. The RBI was exactly as he described (and he provided pictures of all sides), a couple light scratches on the top (typical from racking), but the front and back is spotless. Would buy from him any time and I look forward to any transactions with him in the future.
