Bose and Ipod Docking stations

I have a Bose wave system together with a module to connect an IPOD/IPhone to play music through its speakers, originally I had an IPOD Nano but this was lost so I bought a ipod touch this as you will know requires a 30 pin Docking station and really that's all I want but Bose do not manufacture them, if possible I would like not have to get a docking station with a separate speaker does anyone know if I can get a 30pin docking station (any maker) that would be suitable for this system.
