Expensive in the UK I guess. Could easily get an hour in a 737 or older 757/767 sim for under $300 in the U.S.
Really, guys get lost trying to intercept a VOR radial; they get lost on downwind; they have to spend so much mental capacity to fly the airplane that they can't concentrate enough to do the CRM bits.
EK recruiting want the guys to succeed so a little bit of preparation would help to make the difference for many many applicants.
