HIGH TORQUE MOTOR FOR 4-6-0

[fastfordray]

HEY EVERYONE,

There is a motor upgrade for the 4-6-0 on EBAY for $11.50. Is this a good price or does someone else make one?
It's supposed to be a high torque motor, have a 5 pole armature, heavy duty brushes, and large bearings.
At 12vdc they draw 162mA at 10000 RPM.
Has anyone ever bought one of these motors, are they any good?
The motor is supposed to screw right in.
What about the worm gear? Is it easy to take it off of the shaft, or do you buy a new one?
Need as much feedback as possible so that I don't make a wrong decision.

Ray,

Don't know about the motor, But I can remove the worms and install them.

Also need to know which Big Hauler drive do you have there have been six of them.
