For masters courses In the UK you might want to take a look at:
As for the course/no-course opinions...
I agree with everybody who is saying that a degree isn't going to magically get you respect, make you employable, get you on the speaker circuit, cure acne or make you more attractive to prospective partners.
Remember the people who require a degree for a job also look at the experience of the applicants. So the most experience still wins - the degree just lets you take part in the race.
You can certainly have a wonderful career in the UX field without a degree in the area. I don't have one and people still seem quite happy to pay me :-)
It's certainly not going to instantly improve your skills. Only lots and lots of practice does that.
However - that doesn't mean a degree is useless.
It will get you an instant network of people in the field - your classmates. They'll all go off to different places and have different experiences. Keep in touch. You'll learn a lot.
Universities tend to be full of fairly bright folk. Knowing bright folk outside of your field is useful too. Whether they be in academia or industry.
It can be hard to get a broad overview of a field when you're working in the trenches. If you're employed to do visual design for web apps, getting the spare time to learn how to do usability testing of desktop apps, or ethnographic studies isn't easy :-)
The degree I do have (in Computing and Artificial Intelligence for those who care) I went into after I had four years of industry experience (well - experience of people paying for the software I wrote anyway :-) I'm glad I did that degree since it gave me a whole stack of knowledge and skills that I wouldn't have easily got in such a short period elsewhere. Indeed - it was the cognitive psychology aspects of that degree that were part of my journey to working in UX :-)
The degree didn't make me employable. What I did with the contacts and knowledge I got from there did.
Whether you should do a degree or not really depends on what you want out of it. It's not a ticket to success. It is a way you might get some useful fuel to help you be more successful.
