Rev-N-ator ignition boxes?

seems interesting thats for sure... And according to there dyno tests with different ignition boxes i'm running one of the worst boxes you can run. Because i am running a 4 pin Wells ignition module and it tested below the mopar orange and mopar chrome ignition boxes.
I just need to decide if i wanna get the Rev-n-ator box or Don's box from fbo systems wich also has a rev limiter and a 2 year warranty or if i wanna get a cd ignition from crane or mallory, it would be nice to just plug something into my exsisting harness and go, and have a rev limiter. I'd rather be able to just plug something in and go, so i guess i need to decide between this rev-n-ator or don's box at fbo systems.
