I rode a hardrock sport for 6 years (v-brakes though) and I cant complain about any part of it. It is a very light bike and extremely durable. Specialized is a great brand and im sure you will be happy with it.
However, the only thing I question is are you sure you want to spend all of that money on a new hardtail? Im not exactly how much they go for (~$400)? But, if you look online at some discount bike stores, e.g. nashbar or jensonusa you might be able to get a new full suspension for another 100-200 dollars if you would like one.
But, if you are strictly looking for a hardtail, then yes the hardrock sport is a great bike.
