I went to PAT and found their training to be excelent particularly on the IR course. They aren't cheap granted but the a/c are very well equipped and the instructors have all got masses of experience of both military and civi experience. I had a few problems with a/c availabilty when on my CPL course due to the expected 2nd Sierra not coming on stream and so not enough planes for too many students. As Polar_stereo says they will tell you very honestly if they have space or not and I know they are very full at present cos everyone wants to get through before the CAA system closes!!
just get there before their current sim instructor ******s off cos steve will teach you more about NDB approaches and hold in one sim session than you thought possible!!
All the best
