Timing belt and Water pump brand
 

I'm going to do the timing belt and water pump replacement on my S70 (150k). I'm assuming I should change the water pump at this time with the timing belt given the mileage. What's the consensus on where to buy or brand to buy? I see FCP Groton has a decent deal on eBay from time to time.

Just call them directly, they have Facebook and forum discounts from time to time.
Conti belt and, I think the Hepu pump the preferred pump.
Don't forget the idler and tensioner pulleys for the timing belt.
