Instrument repair / over haul (recommendations)

[freerangequark]

Hi,
I need to send one of my airspeed indicators out for overhaul or repair. How do shops distinguish between overhaul and repair? (I am assuming the diaphram on this one is ruptured).

Can you recommend a good reasonably priced shop?

I searched online and found overhaul prices ranging from $125 to $275.

I would prefer to fix the one I have since its face matches the other airspeed indicator in the plane.

Thanks,
Glenn
