I consider SKF as equal, maybe even better quality than INA. At least from my experience of them in oil field equipment.Gates, ContiTech, and Dayco are all quality timing belt manufacturers. I don't know about SKF roller/idlers -- the only time I ever had a problem with one was when it was not made by INA. I thought all tensioners were made by Litens.
Too many water pumps with resin impellers fail to last a full 100k miles. I will stick with metal impellers.
As far as the plastic impeller versus metal impeller, I have left my comments on the following thread as it is more suited there. Feel free to comment, but I believe I have made my point.

Let's not fill up the trusted TDI mechanic thread with a discussion of plastic impeller versus metal impeller.
