MBA

I have 8 years of experience in telecom and WAN. I currently hold a Bachelor degree from the non-sophisticated school and would like to know if, in order for me to get an MBA, I need to go to a more well known university. I hear two different oppinions:
1- to go to any school, as long as the school is accredited.
2- for an MBA, a school with good known reputation is a must.

I intend to grow into project management, currently with experience + certifications in different technologies.

Thanks in advance for the response.
