After 10 years contracting/consulting I was hearing about qualified techies (inc DBA's) missing out on contracts because they didn't have the correct "buzzwords" on their CV/resume, yes a fault of poor agencies but that's the game they play.
Now myself I have never felt the need for certification, my experience/references prove I can do the job but I took the MCITP 2008 DBA and passed it back in December, yes it expires later this year but I actually enjoyed studying for it, still hate exams with a passion! Learned some new features and now can put MCITP on the CV, and business card. If it helps, great, if not no great shakes. Might even do the 70-433 one before July.
