The motor on my bandsaw went out and after looking around Oklahoma City, I looked on the web and found MROSupply. They had the best price of anyone. I ordered it on Wednesday and it was on my porch on Friday! Awsome Service! James I. McCaslin

The purchase from MRO went smoothly, and it arrived. However, the shipping department needs some remedial training. The box containing the motor was not strapped to the pallet, just set on top of it. As a result, the box rolled off the pallet and was split open. The freight company managed to wrap it up (upside down) with stretch film and put it back on the pallet, but it looked terrible. By a stroke of good fortune the motor was not damaged by this treatment and it looks OK. I can supply photos on request.
