Exhaust Brake:BD or Pacbrake?

[backroad]

I've been trying to do my homework on my Ford/Cummins conversion. I'm building a 518 auto and converting it to a lockup convertor.



Now for the question at hand. I'm having a hard time deciding which Exhaust brake to use with my 1st gen. Cummins.



Any help or suggestions? The pacbrake IS much less expensive.
