MAcc with AACSB Accreditation vs. Regionally Accredited

I am set to graduate from my undergraduate Accounting program in May '15. I'm beginning my GMAT studies during Winter break and aiming to graduate with a GPA in the range of 3.4-3.6. Can anyone enlighten me on the potential benefits of earning an AACSB (or other business/accounting related accreditation) accredited MAcc versus earning a degree that is just regionally accredited? I am really leaning towards regionally accredited to save money and time, but of course I want to make the right choice. If it matters, I am looking at UMUC for my MAcc.
