For all those who say pay for FI's will always be poor because the clubs can't afford it. ...
The back pages of Flight and other press suggest the rules of supply and demand do apply to this industry. Salaries of between 20 and 30 k for FI's and FI(R) (as far as I can tell to teach PPL level).
Enjoy it while it lasts though, pay will drop again as soon as the new PPL/FI's enter the market!
