If you have access to a motor rebuild shop that will do the work cheaply, that would be a great option -- you'd get an almost new motor for -- hopefully -- considerably less than a new motor.

But in my area, the main rebuild shop is no longer a high production facility (most of the big manufacturers have shut down or left) and they now charge nearly as much to rebuild fractionals as the price of a new motor. From a Pro's point of view, that's a no-brainer: use the new motor with a manufacturer warranty: more profit and MUCH lower chance of an unpaid warranty call-back!
