Is this a good motor?

[beaster456]

I have a craftsman 2x42 and its great but I was thinking if I came across a good deal on a motor I would hook it up to the craftsmen to give it some extra power. Is this a good deal? http://www.ebay.com/itm/GE-5K145SC3...669?pt=LH_DefaultDomain_0&hash=item417a5705a5
