Figgs, I just bought the ACE study package. It comes with quite a bit of study material (books, workbooks, DVD, CD's). I called around the Chicago-land area and found that most places recognize ACE as well as NSCA (whether it be CSCS or CPT), NASM, and ACSM. I don't know where in particular you're looking to work but for instance one chain (Lifetime Fitness) ONLY hires NASM certified.
Anyway, good luck with which ever certification you choose.
