Bread-Bakers v106.n027.4

Our church has two old Kitchen Aide mixers that need repair - 
speculation is that they may be 40 years old.

They are heavily used 2 days a year.  I was planning to find a repair 
place in the San Francisco Bay area (suggestions?) but the ladies 
indicated that they may be too old to fix.  If I need to find a 
replacement, they seem to be leaning towards a more commercial grade 
mixer.  Any suggestions are welcomed.

Thanks
Doris
