Education and Training: Which Forensic certificate(s) are most in demand?

I am a seasoned computer professional (25 + years on mainframes, UNIX, Windows platform) seeking to move into the Computer Forensic area. I am seeking a Computer Forensic certificate, please no debates on the value of a certificate vs. experience, I understand the argument. In your opinion, which Computer Forensic certificate do employers respect the most? Which Computer Forensic certificate will likely get me that first job in Computer Forensics? Please add some reasoning to your answer. I will be paying for the certificate education with my own monies, so I do not want to make a mistake. I have searched job sites, DICE and Monster, for how many positions are seeking this certificate and that certificate, but I would like the opinions of many season professionals. In closing, a BIG "thank you" for your time and effort. John Dawson
