On Ebay, but there are two with the cessna on.
This one (8th edition I believe)
Private Pilot Licence The PPL Confuser. Pilot Exams NPPL. Aircraft | eBay
And this one (9th). I have this one and find it excellent, although there are a few wrong answers in there.
The PPL Confuser (JAA) 9th Edition; Neung Sornying - Glynn Stephens. Pilot Book. | eBay
Be prepared to pay about £50+ for it though. They were going for over £100 at one point but have come down again.
