I am ISSA certified myself but decided a few years ago to obtain the NASM certification because of its standing in the industry. Just check it out.
I have had great amount of experience with ISSA, they are great people, very helpful. No cookie cutter certification here, you know that you are in the right place when you go to their seminars and the CE that you need is also the same CE that Chiropractors use for their yearly CE. I am working towards my Master Trainer with ISSA and so far it has been a great ride. It depends on what you want to get out of it, I only had to go outside of ISSA to DSW to get my BOSU Specialty. Hope that helps.
