Where is the best place to buy a replacement electric motor for my furnace blower? The son-of-a-gun finally siezed up on me. I heard it humming when the wife and I got back from Christmas shopping tonight. I found one in Grainger that matches up, for about 125 bucks... but I didn't know if there were any other places around to check. How's that price sound? Its a 1/5 hp DD, 1050rpm, 6.7amps... 1/2"x3"shaft.
