least expensive AACSB accredited doctorate in US or internationally?

[life_learner]

I am wondering what the least expensive AACSB accredited PHD or DBA program is in the US which is possible to obtain while working full time? I would need a limited residency or online program. I am not able to attend a full time program due to needing to work to support my family. 

The least expensive program I could find matching this description is the Bryan School of Business PHD in Business Administration that is online with some limited residencies. If you are not an NC resident like myself, The program costs just over $50k which is expensive, but, it is the least expensive program in the US that is AACSB accredited.

What other international doctoral distance learning programs are AACSB accredited? I know there are several programs in the UK that are AACSB accredited and I believe they are close to the price of Bryan School of Business UNCG. In particular, I am looking at the Aston DBA program.

I know Grenoble is I believe about the same price around $50-60k. 

Any other AACSB international programs with limited travel requirements referrals would be appreciated.

Thanks,

Marshall University DBA tuition around 57k. Limited residence requirement.
West Virginia University DBA in accounting around 60k and there is no traveling. WVU is probably the best in terms of balance of tuition and reputation. I will be starting with this program in the Fall.
For someone who does not mind paying over 100k, University of Pittsburgh DBA is probably the best ranked one. I was admitted to the program but have decided not to enroll due to cost.
