I have a mp 40 that seems like someone converted it to a quiet drive. Has the controller and acts like one, but has the old outside the glass side. I used it for a while and didn't have any ir ran as good as the other 6 i have running. I'd sell it for $250. Then I have a mp40 non quiet drive that I ran until I replaced it with a new one. I'd sell it for $200. Both run great.
