I just finished my masters through Penn State in Geographic Information Systems (better known as GIS) online. I did my undergraduate degree there, in person. There are a couple of things to consider. For me, GIS is entirely computer based, thus I was going to spend an inordinate amount of time in front of the machine, whether it was doing homework, or anything else relating to the degree. Secondly, I needed to keep working, and going to school online guaranteed that I could work on the classes in my own time. Third, this program was established about four years earlier and had an established record- and the number of people attending had grown each year. Lastly, there were a group from my office (initially four, but two that will finish the program) that were pursuing the degree. That meant that we could do an number of the things you can only do when you have a more traditional setting like studying together, asking questions or getting second opinions on projects.
This method worked well for me, and I will be traveling up to State College next month to receive my diploma. This is also important, because my degree will be no different than that of someone who studied on campus. The word online or electronic will appear no where on the degree, which is not the case even for other online degrees offered by Penn State.
A few words of advice beyond what I said above. 1) make sure you do not go to a paper mill university, such as University of Phoenix, or Louisville-Pacific. It will lower the quality of the rest of your resume, instead of improving it. 2) Make sure the field of study (I know nothing of the degree you mentioned) is relevant to the way you will be studying. 3) Make sure the professors will be responsible enough to get back to you quickly. I actually knew some of my professors from my undergrad years and that made a difference in the end. 4) Make sure you are self motivated. You need that to finish any degree, but with an online degree it is easier to push off work.
