online colleges

I am considering going back to school online, however where does someone begin lol. I want to pursue a bachelor's degree. I was considering Western Governors University and Grand Canyon University. I like the format of both schools. Western Governors is the least expensive of most of the online schools. Does least expensive also mean poor quality school? I have read many things online about it but not sure if what I am reading is legit. Have any of you ever received a degree from this school and is it legit? There are tons of websites with reviews or that talks about this school as well as good and bad reviews. Is there a site that has credible information I can trust about the legitimacy of this school and if it is worth the time and money or just a waste?
