You seem to be focusing on large flight schools...in this business large is not always better.

FSA has a good reputation, and since their real business is simulator training for professionals they are not going to doing anything stupid to tarnish that reputation (other large schools have commonly embezzled all of their students money and skipped town, etc). If cost is no object, FSA would be good.

If you want to save money, look at small local schools close to home. That way you can live at home, maybe keep a part-time or full-time job, and train at your own pace for significantly less money. You will need to do your homework about any school (small or large). Obviously talk to the staff, try to get a feel if they are helpful, or just high-pressure salesmen. Also note if they are honest. If they tell you you'll be flying a widebody jet for a major airline in 2-3 years or other outrageous lies then run away. Also avoid schools which want massive amounts of money on deposit in advance...if things don't work out you will have a very hard time getting that money back. Also note that few students finish all training in the minimum amount of time required, plan on needed some extra money for that.

But the most important research you can do is to talk to current students and CFI's. You will want to do this out on the ramp, or in the parking lot away from management so they feel comfortable being honest with you.

In these days of fewer opportunities for CFI's you should also chose a school which has a very good chance of hiring you as a CFI, and preferably does multi-engine instruction too. Ask the students and CFI's what are the odds of getting meaningful CFI employment after your training.

Also high cost does not equal quality, and quality does not equal better employment prospects. Someone will lie to you about this, but unlike traditional education where a "name brand" school means better job opportunities, aviation employers ALMOST NEVER CARE ABOUT WHERE YOU GOT YOUR TRAINING, unless it was US military flight training. Employers care about ratings and hours only so look for the most cost-effective means of getting ratings and seek out the kinds of jobs which will provide the experience you need (multi-engine and/or turbine).

If you burden yourself with large debt, in a few years you will be asking yourself why the heck you did that when the guys sitting next got to the same place just as fast with little or no debt. Aviation no longer pays well enough to support student payments.
