Depends on what you're looking for. Are you going for Bachelors or Masters? University of Houston, good school, does both completely on-line if you want. Their prices are reasonable. I looked into getting my masters at a few places and UH was the best all around. I went through a list and several were over $20k a year for online!!!!

Give them a look and whatever you do DON'T GET SOMETHING AVIATION RELATED.

Edit- It should also be noted not to do searches for the "best online universities" etc. Some places specialize in that and that's all you'll find. A lot of universities are moving on-line so find a few near you or that you know of and contact them via email. You'd be surprised how many have those programs setup. My Baptist university even has one!
