This plugin pushes items that lie on a Workbench automatically into a Chest or Dispenser.

The Chest/Dispenser can be seated directly besides the Workbench or be connected to it via Redstone Wire of infinite length.

Multiple Chests/Dispensers can be linked with Redstone Wire for in case a Chest/Dispenser is full.

Filtering is possible using Signs within the Redstone Wire line labeled with the english name of the Block/Item (see http://www.minecraftwiki.net/wiki/Data_values ) or its decimal ID to let that type 'pass' that Sign.

You can also use common parts of Block/Item names to group them, like "stairs" will fit for wooden, brick or stone stairs.

Filtering multiple Blocks/Items is also possible by simply separating their names/IDs by comma.

A nearer chest/dispenser is prefered over a more distant chest/dispenser, EXCEPT there's a sign involved: A filtered chest/dispenser is always preferred over a not filtered one!
