Can anyone suggest a good, reputable university for online PhD degree?

Start with good, reputable universities - many, if not most, offer online programs nowadays and fulfilling the campus requirements for a history major shouldn't be too difficult - a lot of campus' cooperate with each other. Find out which universities have the best history grad programs and see what they offer online.

My husband, Rational Gaze here at TWeb, wants to pursue a PhD in history. He is about to get his Master's degree this year and will be ready to start on a PhD this coming school year. The original plan was that he would remain at the same university, but it's looking like I won't be able to move in with him after all. We are looking into him moving to the US instead and getting his degree through a university that offers courses online.

Can anyone recommend a good one? We need a reputable university that does not charge an arm and a leg. What should we look for in choosing one? What are some red flags indicating the school is no good?

Any help would be appreciated.
