There are some courses being run at Scubadive West up in Galway during the year by some GUE instructors from the UK. The 'GUE Fundamentals' courses will be run in June, August and September. See http://www.dir-ireland.com/index.asp?LCID=1&PID=17 for course schedule.
If you want to know a bit more about the course, what it involves and what you get for your money then have a look at the following link and you should get a better idea. I did the course so if anyone wants any info from me just ask.
