Onkyo ABX-100

Hi

I have been looking for an ipod dock and have come accross the Onkyo ABX-100. Has anyone listened to one and compared it to other docks in this price range? There is also the Onkyo SBX-300, Yamaha PDX-60 or PDX-31 I have been also considering.

Does anyone have an opinion and advise on these or some alternitive suggestions?

Thanks

Ryan
