I did my IR in Spain and from my experience I would say to anyone, not to do it.
Instruction was quite poor and a lot of very basic stuff was not covered.
I also found the language barrier was a huge problem. I would ask a very very simple and clear question and it was not being understood. Only for the fact I brought a good few Instrument books with me, I would have been in quite a spot. When I came back from the course, I did a lot of work when I got back to get things up the standard that I was happier with.
If you don't have the cash for the training in the UK, save and get the money together.
Believe me, it is not worth the heartache.
