You have to be careful. Sometimes, saving a buck on the front end doesn't mean that you will save it on the back end as well. Some schools in the US are of quality, some aren't. I have came across students (who have trained in the US) who lack basic skills. We are talking about 'Effects of Control 1&2' here, not more complex tasks like flying an NDB hold with a 35kt crosswind. The first 10-20 hours of a students life in an aeroplane are the most important. You don't get them back.
Do your research. Look at the arguments.
