You do not pay for the flight instructor part, you work as an EFT employee and receive renumeration ($10 an hour), the hours aren't guaranteed. A friend at my local flying club went through EFT using the modular route and was asked to be an instructor for them because they were so short (this is normally only available to cadets on integrated courses), I hope this is still the case when Im out there!
I appreciate that a current FI with 1000+ hours is a benefit, what I am trying to ascertain is the value of that benefit when considering airline recruitment, for eg in 18 months I could have worked full time in another indusrtry and nearly saved enough for a type rating, or purchased some sim time
