Sussex Flying Club has a good selection of instructors and the aircraft are reliable. I would not be against having a lesson or two with more than one operation as you may just click with one instructor. Have fun, Shoreham is a bit of a challenge for the novice but you really will learn how to handle traffic. ATC can be a bit Heathrow sometimes but they are really helpful most of the time despite being run off their feet over the weekends. The runway is really narrow though but that just adds to the fun.
