Yea I'd recommend checking them out. I've been looking for cheap timing belt/60K supplies for a while and the money that you save on just the two pulleys ($12 a piece as opposed to $60) mean that you can buy everything else at stealership prices and still save money. I will still be spending money where I think it needs to be though, like OEM valvecover gasket and not buying a ebay waterpump. I've been happy with the quality of other seemingly to cheap to be true things from them in the past.
Just looked and their waterpump is $50, if you know of a more trusted brand/vendor for simliar price I'd consider it. Also BTW none of the stuff on their site is remanufactured unless it explicitly says rebuilt in the title of the part, like their alternators. I'm not sure if you meant that brand name would make a difference in waterpumps or if you thought they were rebuilt at that price.
