as much i know and information i have, they are very very good! Nice reputation! I was also thinking to go there for my PPL+IFR/ME, but later changed to Spain, just to stay in Europe (because i hate to make visas to another countries,go to the embassy etc.). As FAA PPL student need visa and there is no US consulate in Munich i just left that idea...
But as for USA, RFC was first choice for me
