I concur with the last poster. If you do not require the visa through PEA, then American Flyers should work out to be much cheaper. However PEA is very good quality, but expensive.....less than FSA ,DCA, and ERAU but not many others!!!
Some friends of mine have/ are still training at Epic, which is a similar but smaller setup to PEA. They recieved a very a large discount for paying in advance and the simulator rates are very, very reasonable.
However paying in advance does pose CONSIDERABLE risks whatever the age and reputation of the school.
