Well, whatever you decide to do you'll need your PPL at some point...so if you decide to invest in those first 5 hours..then feel free. They'll always be there wether you decide to do your next bunch of hours pretty soon or in 10 years time.
Don't know if you've had a taster lesson or not yet, but definately invest in that before paying for five ormore hours...just incase theres the slim chance you don't like it!! Best of luck....its an expensive business, but worth it!
