This is probably not the best forum to answer that question, but some of the best advice I had before I went into my own MBA was to ask myself what I wanted to do after my MBA. Knowing what I wanted to do after the MBA helped me choose the program that would help me reach my personal goals.
I think the same is true in your case. What do you want to do (what job do you want) after school? Do people in that job (or similar jobs) have an MBA or MIM? If there is a high percentage of MBA or MIM, you probably have your answer. If it's an even split, you may want to talk to people in those jobs to see what they would recommend.
Can you PI. suggest me some good forums where people can suggest me about good MBA/MIM institutions???
