I used a MMF-7 for close to 18 months. This is a very good table and a real bargain if you can pick one up on the used market. Be quick 'cause they go fast. I sold mine within 8 hours of placing the ad here on Agon. It is true that there is not much you can do beyond a few tweaks to the Music Hall tables. I have heard from many MMF 7 owners that love thier tables and have no plans to change them. IMO, the MMF 9 is not worth the extra money as there is just not much difference in performance when compared to the MMF 7.
With the Rega tables you do have more options to upgrade the arm.
