I graduated from UT-Austin's evening program in 2006.
I look at MBA programs slightly differently. It all depends on what you are going for. Some initial thoughts to consider.
1. Most of the people that graduated with me moved jobs and maybe made 90k, but with 50k of debt you have a negative ROI. Unless you have some specialized skills or are planning to go into a high income job after graduation you will probably end up negative from a financial ROI standpoint (if you have to pay everything yourself)
2. You only really get one shot to go to an MBA program - and the name of the program stays with you for life. Some industries care where you got your MBA from, some don't.
If you are going to get your MBA to go into a specific field then you should get the MBA that allows you to get there with the least debt.
If you are going just to change jobs/industries (but you don't know exactly what jobs you will go into), you need to seriously consider the ROI vs your displeasure with your current job. It may be better to get a cheaper MBA or wait till you can't get on with a company that will pay for it (or part of it) - if those type of companies still exist (none that I know of now)
If you are just going to get an MBA just to get one (I would not particularly recommend this, but I don't know everyone's situation), go with the place that creates the least debt.
There were 100k new MBA's being generated every year when I graduated. There are very few 100k+ jobs (starting salary) compared to that demand. The ideal situation is to get on with a company and let them sponsor you (full or part).
I have friends that went through it, changed jobs (maybe 15k increase in salary), and are financially negative - but would do it again in a heartbeat since they love their new jobs. Others stayed where they were but now have a nice 50k debt payment (and all they got was another diploma on the wall.)
I don't want to come off negative against MBA programs, but the expense of these things truly outweigh their rewards in many cases (just like 2nd/3rd tier law schools - 60k salary for 100k debt)
I got my company to pay for mine, so I went to the best place I could get in (which was UT-Austin). The MBA has allowed me to further my career more than I could have imagined - however, I don't think I would have done it if I have to pay 100% - I would have found a way to be happy without an MBA. But then again, everyone has different reasons for going - you just have to figure out yours and make sure the MBA program matches those goals.
