If you want seriously cheap hours, and you have a few weeks to go to America, go to one of the flying schools, find out what it costs to rent a 152 wet, then offer to rent the A/C for say 50/100 hr block dry, and tell them you'll pay by the tacho hour (which they'll probably accept). You should be able to get a 152 for $35 - 40 per hr dry, and fuel is around $1.80 - $2.40 per gal. Then go into slow flight and fly long cross countries (tach proportional to rpm). Of course you log chock to chock, but pay for tach.
