Hi ajec
I finished my training a few months ago from epic."Guarantee" is true they wont charge you a dime over what they promised...but i think they can remove you from the fixed price if they find you incompetent(no shows, solo above 100hrs,etc...) Atleast that was the case when i was there...shouldnt be a problem if you study and show some effort.
They have an excellent well maintained fleet. Especially the new nav3 172s with g1000 keeps thing much safer with all that traffic. The instructors were great...i never had to change my instructor, went from 0-280 cpl multi/single ir with one instructor.
Let me know if you need any more insight.
Good luck
