Sorry, Gonnabe, what I was getting at was which airline you're aiming for. Obviously, if you want to get a job on an airline operating glass 737s, getting a rating on the -200 isn't a lot of use. There may be airlines operating the classic 737 where you are, but there aren't that many in UK. If you must get a rating, do it on an aircraft type relevant to your intended future employment.
