You need to consider what school you're talking about. An MBA from anything less than a Top 20 is almost worthless. I thought about a JD/MBA, but decided not to do the combined program because my school's MBA program is not even ranked. I'm at a T-20 law school, and I'll likely be starting at a T-5 MBA program right after I graduate from law school. I know it's a lot of school, but an MBA at anything less than a T-20 is a waste.
