I did my hour building for £79 (about a tenner cheaper if you fly to France every day and make use of the duty free fuel) inclusive landing fees etc via a dry lease in a newly refurbished and painted C-152. Great fun, managed to fly from London to Glasgow and back a couple of times as well. The best part of a dry lease is that you have exclusive use of the plane, no sharing or waiting around plus it's only airborne time you pay for.
the company is called big red kite aviation, Keith, the owner, is a decent bloke, it's worth having a chat with him.
