Have you guys pulled it apart yet? Is it noisy like a vibration...or does it just sound louder than normal.
Not 100% familiar with that particular bandsaw, but it's possible the exposure to SW might warrant just checking the belts and pulleys to make sure they are still moving smoothly. Of course...that depends on whether it actually runs on belts and pulleys
Whether you decide to fix or sell...easiest thing to do is to remove the belts (or just the blade if that drives off the motor) and see if it still makes noise. If it does...then it's likely the motor bearings...if it shuts up, then you may just need to lube the pulleys, check the shafts to make sure they are still straight, and/or replace the belts.
