Research MBA Programs

I have a BS in management and I want to focus on a MBA with a concentration in information systems. My main work experience has been working for a software company so i naturally have an idea of what IT is. I didn't work for long with the company about two years to be exact and i have not worked for about 5 years now. I am deciding to go to get a MBA and thought that would help me get back into the job market. well your advice and opinions would be greatly appreciated. I got a 550 on the gmat not the best but it is going to get me into Cal State Fullerton (california) and with that I should be able to land a job in the southern california area.

thanks
