Wanting our own offsite backup solution

[VanCity]

The mandate is to backup approx 50gb initially off site and any new/modified files after the initial backup is complete.
15 workstations/1 server all together.
Ideally I think I want to back up all the work stations to a backup area on the server, then copy this folder(s) along with the server files through out HotBrick router and to a machine that has a Lacie 1TB raid drive.
So what I require is suggestions on what software(s) to use which are the most cost effective solution as saving money is the reason I have been told to get this done!
Any help is as always appreciated.

I forgot to mention the Workstation are WinXP & the server is SBS2003.

Galaxy Express from Dell is quite cheap

Amanda is free and would only require a Linux box to act as the server. (And a bit of reading)

Lots of folks use it but enterprise size folks are still gunshy when it comes to open source apps

Commvault Galaxy is great for windows
