Hi, pivetta,
I have a Music Hall mmf-7 (with Pro-Ject 9 aluminum tonearm) that is 11 years old and still running strong. The Pro-Ject tonearms are relatively easy to set up and accommodate a range of cartridges.
If I was upgrading my mmf-7 'table today I'd be looking at the Pro-Ject Xtension line of turntables rather than the dated Music Hall turntables. Just my opinion.
Regards,
Tom
