Can't comment on their CPL/IR training, but as a couple of others have said, good school, nice people, they now have a base out of Barton Manchester but I believe this is mainly for PPL training. I did my PPL with them and they were very professional and knowledgable. Their is a sim at Salford Uni that Ravenair are using, I have just graduated from the uni and is a pretty impressive bit of kit!
All the best,
Craig
