Best network backup solution

Looking for a general consensus on the best backup solution for a network of 20+ workstations (XP, Win7, and Mac 10.5) and one server (Win Server 2008).  I would really like an image to be taken of all the machines on a semi-regular basis to make for easy bare-metal restores, but still be able to restore individual files quickly if needed.  Any thoughts would be appreciated.

By the way, I need the software to make it all happen as well as a good network storage device. Hoping to keep the total cust around $2,000.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
