Just had mine done about 2 months ago, they would've charged me $750 for belt, pump and labor (I ended up having additional work done at the same time).

Kit they used was made by Gates. The shop specializes in Subaru SCCA race cars, and they're all running these belts on their personal vehicles so they felt pretty strongly it was a quality part. Little sticker they put under the hood to show the work done says it doesn't need to be replaced for 100,000 miles.
