Well, since the Fuze was the last player to offer a 30-pin connector port and it is long discontinued, I think it’s highly unlikely any 3rd-party company is going to make anything dock-like as an accessory. That’s why the Sansa Base Station was discontinued and you can’t find them anymore.
All the newer players connect via either a mini or micro-USB port on the side, so again nothing will be made as there is no market for such a device.
