My college mentor always said, "do not pay for a Master's degree, find a company who will pay for it." Best damn advice I've ever gotten!
Every company I've every worked for offered money for education but usually it only covered slightly over 1/3 of the total expense when everything was said and done. (And this was early 2000s when University was cheaper)
Also, two companies required at least a B for reimbursement which is not always that easy in a competitive STEM class. I found I could do work, or school, well. But not work and school and subsequently dropped out of my Graduate program. It worked out in the end. :)
