What are my Front End options?

In the planning stages of a '64 cuda build, and through this forum have seen the Alter-K-Tion kit and the Magnum Force kit for front end coil overs / K-member replacement.

My questions are:

(1) Has anyone here had experience with both, and if so, are there any pro's and con's that you've come up with?

(2) Are there any other options out there (besides building one from scratch).
