Query: Porter-Cable 7336

This is a very nice unit. Works great. Would have given it 5 stars but I am afraid that the bearings may burn out relatively quickly. I've had problems with them in the past so I tried a more expensive Bosch unit. What a piece of junk. It burnt out in 2 months of light use (wet-sanding). Repaired under warranty and burnt out again 9 months later with MAYBE once a week use. I'll stick with the Porter-Cable from now on.
