I'm in 50k debt for my MA. Although I do not regret doing the MA (it led to some amazing things), at this point, I would not chose to go into debt for my next degree. It's hard to have that money hanging over my head and knowing if I pay the minimum payment over 20 years, it will double my total payback to 100k. I wasn't smart about money the first time around, but I'm determined to be next time.
This all being said. An education is not just about money and landing a job, it's about the experience of learning and growing in an intellectual community. If that is worth 100K to you, then go for it.
