 Personal Opinion (no commercial connection):  The APS course is well worth
 the time & $.  Lots of data, experience, hands-on examples, etc.  Good info
 on LOP operation and good info on using engine monitors to diagnose all
 sorts of flight/engine events (LOP and ROP).  Walter, George, & John have
 put a ton of time and energy into making it as valuable as possible.
