DSLAM writes "Which certification would be in most demand (and therefore more lucrative) in the IT market for the foreseeable future? I was looking at different certifications from Cisco, and Microsoft and also various Linux ones. I'm more interested in the networking aspect but I'm also open to all suggestions. About me: I'm 38, male, Uni graduate in Psch, married, no kids but hope to in the next year or two, wife is preparing for med school, I do freelance video editing. I spend hours messing around with my computers, running Suse Linux, Windows and Mac at home. No other computer expertise beyond basic home networking, and getting my torrents working with no NAT blockage. So I wanna go further but I want to make sure I invest my time in something that will be financially worth it. Just how hard is it? How long does the preparation take for the different certs?"
