Join the CAP. I'm doing my PPL right now and it costs me about $53 an hour. I also have 6 free flights from Orientation Flights that I can use each year. In the end, I'm looking at spending about $1600. At 200 hours you can become a Mission Pilot and Cadet Orientation Pilot, and there's free flight time right there. I will probably end up doing my PPL and IR through CAP and then going to the local FBO for my Comm.
