1. Did the job
This did the job. Had a bit of trouble with the 4mm press rod, as it broke after pushing the pin out of the old chain. Motion Pro's Customer Service about the warranty was GREAT, and after sending pictures of the broken pin, they're sending me a replacement piece.
Also had problems with the Master Link (2-hole) press rotating and making it difficult to keep the new Master Link pins aligned when I was pressing it together.
