I don't have a ton of experience with Western Governor's, but the fact that unlike many online universities they are nonprofit is a good sign. Of course, whether they have access to quality instructors is an unknown to me.

(Edit: from what I have read, I don't think there are different tiers for tuition, but it is all the same. Corrections welcome. I think it is quite low, for any student, so the opportunity including for international students in lower-income countries is significant.)
And for WGU, there were praises of it on this page from former students (https://news.ycombinator.com/item?id=22719797 and Ctrl+F for "wgu"), and a relative of mine is planning to attend soon, but I can't say from personal experience. I would certainly hope they do a good job. At the very least, they are accredited and one can use that credential to earn money while continuing to learn well from many available sources (like MIT online courses, unix system documentation, etc :).
BYU Pathway Worldwide and associated programs. It requires a Church affiliation but not necessarily membership (I think). I think tuition is much lower, bachelors programs (like IT, business, others) are available, programs excellent, and is also suitable for those who need to first become qualified for entering a university (edit: i.e., learning English which is used in curriculum, and other basic skill), then provides that university. More info is in Wikipedia and I have gathered a bit of info including linking to a news article that explains it well I think, here: http://lukecall.net/e-9223372036854578440.html .
And: https://www.wgu.edu/ (also mentioned in wikipedia): state aid available from multiple states it seems (per wkp).
