I would say you need to try and get in to a carrier now. Loco such as Ryanair will be recruiting for some while yet as they still have 130 737s on order. The slowdown is happening and money is getting tight all round. if money is tight then the punters won't spend it at the flying clubs. Flying training is getting more expensive every day with prices of fuel. If you are in the position where you can afford a TR with a GUARANTEED job then get it done. Don't worry about salaries at the moment or what you fly. if you want to fly professionally you have got to be aggressive with your career.
I was looking during a slowdown between 99 and 01 and luckily got in before 9/11. Wasn't a fun time but I did instruct part time while keeping a few bucks rolling in with a full time job. Was it worth it ? Oh yes !!!!!!!!!!!!
