How can I fix my son's Klipsch Roomgroove ?

The Klipsch Roomgroove Ipod Docking Speaker System was damaged when my son moved into his flat. The docking part has broken away from the main body. Klipsch say it cannot be repaired only replaced but this was an expensive piece of kit. We are quite prepared to pay for the repair but don't know where to go or how to do it ourselves.
