I second WtD's opinions. If your gonna pay your own hard-earned for a course, then first make sure it will be recognised by your potential employer. There are those who still attempt to sell their own course as the one which is or will shortly be the industry standard when it is not.
I suggest you do a search for previous threads on the subject and read very carefully....
While the FAA course is obviously not a UK standard, it would probably count a hell of a lot more at yer interview than something nobody has heard of. (Or have heard of at great length on these hallowed pages.)
