Wanting to return to university, but I have a Master's degree. Funding options?
The only thing I can add to jakebeal's answer is that, it is generally only true for STEM research masters. Most coursework degrees, even in STEM, are not funded. It was unclear from your question whether you were thinking about doing a second masters with a research component, or just looking to get a coursework masters. 

That said, if you are looking for a research masters, I agree with jakebeal. However, I don't know of any school or organization that will fund a coursework masters.
