Not sure where abouts in the country you are, Beethoven, but if you're somewhere in the Northern part of the UK, you couldn't do much better than Prestwick Flying Club. They offer low-cost temporary membership, PA28s and extremely good instructors. They are also one of the last of a dying breed of not-for profit non-commercial members' clubs, so the flying rates are about the lowest you can find. I know that Prestwick now has a control zone, but the procedures are extremely simple and the volume of traffic is low. It would help you build up your confidence with ATC whilst allowing you to concentrate on your flying. A very good compromise!
