I bought a Nakamichi AV-7 several years ago to use in my office and my employes and I are very happy with the quality. I purchased it new on U-bid and for the price I just couldn't pass it up!

If you request sheet rock screws every 6 inches you will pay extra! This is a good idea, however hangers do not normally place screws that close together. I would also suggest having soundboard installed on all walls that back up to any bedrooms prior to sheetrocking. This will help...
