I have the Record Doctor II which is made by Nitty Gritty for Audioadvisor. Its the manual version so there's a little work involved to get the records clean. I just recently purchased it used right here on the 'Gon. I cannot express my enthusiasm strongly enough for the new level of enjoyment that it has brought to my vinyl playback. It has made almost every record I have sound alive. No, it doesn't eliminate the sound of wear, the scratches, and other damage that can be audible on records. But, it has shown me that much of what I thought was wear, scratches and other damage that I was hearing was, in fact, dirt. Many of my records are in much better shape than I had realized or knew. The Record Doctor gets them so clean sounding. I've played more than a few records for my wife who kept asking me, "are you sure that's not the CD"--the machine gets them that clean. (It couldn't, however, save her copy of Carol King's "Tapestry" which she must have danced on when she was in high school (actually never heard a record in worse shape than her copy)). For me, the Record Doctor has brought a whole new level of enjoyment that I never thought possible and that makes it almost priceless. I don't know how anyone who listens to records can live without one. Highly recommended. And, thanks to John for showing me the light. I owe you one.
