they are easy to rebuild too. i'm acutully thinking of starting a rebuild service for locked up vts motors. i just rebuilt the one on my xp. it takes a while but if you got the time it saves some money.
lots of anti-seize on the gears, wire brush to clean the brushes in the motor, rtv gasket maker, peft eletrical greese, and a 12v power source to run it on the bench.
