Help / Advice? Does anyone list the DVD Mega Changers (300 discs or more) available today in the UK? I currently have the Sony 860 (300+1) but have now filled every space! have seen threads about the 875 but where is it? Have also heard that Pioneer and Kenwood have changers but I can't find them! would like to buy anouther sony so I can link them together, anyone know if Sony are due to release a new changer?
