Naval War College, Newport, RI. Free (doesn't get any cheaper than that.) RA. Has a DL-only diploma program, and a mixed-format MS. The catch, of course, is that you need to be a military officer or a senior civil servant.
Cheapest MA Sheffield Hallam University; MA Imperialism and Culture. I did this one it takes two years. Roy Maybery
