Reference John W. Miller's post on player piano repair rates.

What difference does it make?  If both technicians get the job
done correctly, you have _saved_ money.  Would you rather have an
inexperienced person (cheap $$) work on your piano, and damage
something, and then you have to pay 3 times over to have the repairs
re-done right?

I should think that the majority of piano technicians are highly
skilled, very intelligent, and basically honest.  If the technician
refers to a technical manual before doing the repair, it only
shows that he has the sense not to rush into the job without some
forethought.  I would rather have the peace of mind knowing that a
technician with the proper skills, training, and tools is repairing
my piano.

I have always subscribed to these two ideas:

1. "A laborer is worthy of his hire", and
2. "The quality of the repair is remembered long after
    the cost is forgotten" .

Just my 2 cents worth --
