It's a question that continues to gain more and more national attention - what is the real value of getting your MBA? I'm not going to really get that deep into the debate, but thanks to Boston.com for linking to a Yahoo Finance story today that highlights this argument.
There is value in any Graduate level degree, you just need to make sure you are getting it for the right reasons. There is no easy path to evolving your career and an MBA is just another tool that 'could' be valuable later down the road. I will agree with Trunk that you should only enroll full-time at a top-25 program (possibly higher than that). Once you drop out of the top programs the education is the same, but you've lost out on the prestige a big-name school will bring.
So MBA or no MBA - that is the question!
