Actually an online MBA is worth less than a bachelors from an accredited university. If you really want to get your MBA go to a good school. Just make sure you do good on the GMAT. Kaplan has a class to help you study for it. It cost about $1500. Check out this link
www.cgsm.org. They pay everything except room & board I think. The schools that participate in this program is Cornell, Dartmouth, U of Michigan, USC, NYU, etc. This dude I used to work with put me on this site. These are some really good schools. The only drawback is that if someone is working a FT job they would have to quit b/c they want you to go to school FT. Good luck!
