Allied has Alpha 2 pair 16 Ga with shield type 5610B1602 at $544/1000'
which is a good price. I don't know if they can sell 100' spools of that.
This is with one overall shield. It may be a lot cheaper to use a 24 Ga cable
for the tach, and a single shielded pair for the motor (for servo applications).

Allied has Alpha 4 pair 20Ga 5620B2004 with individually shielded pairs
at $557.60/1000'

These are from last year's catalog, so the price may have changed.
