As a software engineer your earning power will be extremely high, especially if you make wise career choices. 60k debt you can pay off in a single year when you have a decent job. The opportunity cost of not being in industry for a number of years is way higher than anything else, so if you want to focus on the monetary aspect it's the opportunity cost you should be concerned about, not the cost of tuition.

Some of these have quite good reputations too.
Even now I toy with the idea of taking a year off and just travelling somewhere to do another one. Something just plain interesting. Modern Japanese Literature, for example, or just identifying a few universities with cheap rates and picking something really interesting out of their catalogue.
If you do it for yourself, out of interest in the subject and because you just want to be better than you are, at that price it will be worth every penny. There is a frame of mind that struggles to comprehend education for the fun and satisfaction of it, rather than as part of earning more money. I smiled politely and stopped talking about it with them.
