FlyingTime at Shoreham have what they call the '79 club'. Basically you get a Piper PA28 (diesel) for £79 per hour including VAT and fuel. Not bad at all!!
There are some caveats on this deal though, such as you can only have the plane for a max of 1.5 hours at a time, allocated in slots. However, I think it's the best deal going so I will be paying the £350 deposit to join this club once I get back from the States with my PPL in May.
Also, if you're in this neck of the woods we could always meet and plane share. This would help to build air experience and we could share the costs somehow which would make it cheaper for us both. Just an idea....
