You're right Spin, I would love to know of anywhere you can hire a Cessna for $150 per hour. David Isaac, are you able to prove that? You will find it is closer to $200 per hour and if you fly out of Archerfield the landing fee for a 152 is $28.00.
Hiring a cessna 172 will cost more like $250 per hour.
Let's look at the value for money you get:
I think $150 for a brand new tecnam is not too bad, with GPS and glass instrumentation AND not forgetting that the tecnam is bigger inside and more comfortable than a Cessna, needs a smaller airstrip than a Cessna, climbs at nearly 1000fpm (lucky getting 500fpm in a 150) and cruises easily over 100knots you can go further, quicker.
The Drifter will always be my favourite though.
