I think I did it earlier in this thread, but I'll send out another plug for Troy again.
9 week terms. In that term, you'll write about 3 papers or so, plus a final. You have to take at least one proctored "exam" per term, usually the final, and it's usually in the form of essay questions (no surprises - they generally come from discussion topics from the term). Instructors I've had so far have all been PhDs, and they are all very willing to teach, interact, and most importantly, work around your hectic schedule. I spend probably a collective 3 hours a week or so doing stuff for class, between the reading, posting the usually-weekly response on the discussion board, and working on papers. I don't think that's too bad of a workload.
The downside is that I have to fork out about 300 bones per class, after TA, with them. It's honestly that big a deal. I put aside $75 per payday, and that takes care of tuition and books. On the other hand, it's an MS degree from a known school that you can actually walk into (ie, not just a PO box somewhere). No disrespect to TUI/AMU/whatever, but I wanted it to be user-friendly, check-the-box, and applicable OUTSIDE of my PRF. I think Troy fit the bill in all of those categories. The other programs I looked at and participated in (AMU) did not.
If you are just looking to check a box, though (not what I would recommend), AMU and TUI seem to be working for a lot of people.
That's what she said!
