perhaps people should give stapleford a break, the prices are clearly stated on the web site (flyingpresents.co.uk), 159 for an hours trial lesson, 9.99 if you want a first flight certificate in a pouch with a few other bits. perhaps if they hadnt cut a deal for the certificate they´d risk offending the next guy who might have paid.
wrt prices lets keep in mind that stapleford is inside the m25, not the cheapest area in the country, doesnt charge landing fees, and the instructors arent bad either.
