well i cant comment on a lot of flight schools in the US, except the one where i went for training myself, Bel-Air International. Good school, 4 172s, 4 cherokees, couple of duchesses, a complex piper and a recent addition, a C-182 glass cockpit. Very friendly staff, planes work most of the times, good mechanics when the planes need service, will arrange accomodation and stuff, quite a few Indian students too if it helps.
The flight school is located in San Carlos Municipal Airport (KSQL), part of the SFO bay area. Gorgeous weather for 10-11 months a year. Extremely heavy traffic most of the time and a class bravo airspace right above you makes sure you're alert whenever you have the controls.
The cost might be a little on the expensive side, but all in all it was a wonderful experience!
