The second Jegs one listed is the closest one I see to a MP unit. It has full mechanical adjustments and the instructions recommend the MP advance kit so it uses the same keys and springs to adjust it.

The first Summit one is made by Proform, junk, there are no adjustments and the advance springs are completely different from the Mopar units, so the kits available don't work. I am done fighting with mine and going with the Jegs unit. I am not familiar with the other two.
