Aberystwyth University, founded in 1872 as the first university in Wales, has been climbing in the world rankings recently and is now in the top 350 (https://www.timeshighereducation.com/world-university-rankings/aberystwyth-university) on a par with universities like Essex, Kent, Orgeon and Connecticut. It now has a campus in the island nation of Mauritius. Its AMBA-accredited business school runs several undergraduate programmes there, and an MSc in international business. The MSc's international fees are just 6,000 pounds a year and the website claims: "Low cost of living - from US $275 monthly with affordable accommodation, free public health care, subsidized transport." (http://aber.ac.mu/why-study/).
For someone looking for a good quality UK education at a low cost, and who does not need intensive careers services (Skype support from the UK is available), this could be an interesting option in a beautiful and multi-ethnic setting.
PS Another excellent option on the island is the ESCP Masters in Strategy & Organisation Consulting: http://www.medineeducationvillage.com/institutions/international-institutions/escp-europe/escp-europe-courses
