What are you trying to get into? Networking, Desktop Support/engineering, network security? Do you have any IT experience? The IT field is always hiring, I haven't had a hard time finding jobs in the field.
If you are new to the IT industry I would recommend getting your A+ first, that's a pretty universal certificate that lets you work on warrantied systems and is the easiest to get. From there you could land yourself a Desktop Support job which is a good way to get your feet wet. Most companies like to promote their IT personnel to other positions so unless you have a bunch of experience it's kind of hard to land those lucrative jobs. Also, before you go blowing all that cash on those certs remember that certs like CCNA and Security+ you have to re-certify every few years so don't take them unless you need them currently. I would recommend the A+ and Network+ to get yourself started. Also, if you know the material for the most part and don't want to study for hours on end about useless information that you will never use invest in
http://www.testking.org you can purchase the actual questions from the tests and study off of those.
Other advice I would give to someone getting into the field is do not take a help desk position, you will hate it and learn absolutely nothing but how to act calm while dealing with irate people yelling at you. If you are married I'm sure you already are an expert at this.
