 Mike -
 
 I recently had my MTV-14 (4-blade, 190cm) prop completely overhauled and
 retrofitted with the new hub grease seals.  Total tab was $3467, which
 included charges from my local prop shop to disassemble, ship, and
 reassemble the unit.
 
 MT's labor for the hub mod was $250, parts were $720 (some of which may not
 be needed for just the hub mod), and expedited shipping was $350.  That adds
 up to $1320, leaving almost $900 for your local prop shop's labor, which
 seems high.  I would think you could get the hub mod done for more like
 $1800.
 
 I've probably put 25-30 hours on the plane since the POH, with no problems.
