The lab I managed used Noritsu machines and we regularly processed 120 for those customers that wanted it done. Once I managed to find a neg gate for 120 printing, offered that as well, although most only wanted their film processed and then they printed their own prints or asked me to send off for 8x10" enlargements of the negs they selected.

If you find a good lab that takes pride in what they produce, and how they maintain their machinery, you'll get excellent results once you've established a rapport with them.
