That's pretty expensive. I wouldn't know which one to go for. Sounds like a very personal decision, although I imagine that the pure engineering ones might be better for you to get that dream job. I have two Master's degrees myself. One in Criminal / International & European law, and then an LLM in IT & IP law. They were definitely worth it for me, although I didn't have to pay as much. The 6 years of higher education were tiring though.
