Surprise Number 2

Ok, so the clutch wasn't happy from day one. When I received the car it wouldn't go into gear while the engine was running at all. Decided to drop the box and inspect.... and here's the damage... All 10 pads have become dust, worn right down to the rivets, some of the backing plates have sheared off and lodged throughout the pressure plate. Its just a mess. So is it worth rebuilding or what clutch do I get next...
