The Netjets opportunity is an incredible one, and one with very real results at the end of it. Sure, the monsters it creates on the "Check me out I'm a Netjets cadet" may have certain people squinting with embarrassment, but never the less, it's one of the most assured schemes out there. Integrated modular has been discussed many, many times, you pays yer money.
Everyone has a story to tell, everyone can raise exceptions, whatever works for you. I'm a happy mod who's total time training will amount to about 10 months, good enough for me. There are a million factors as to ones choice, mine was, "lets get this done properly and lets get this done quickly", but for many with more time spare, Integrated works wonders, not to mention the rather handy finance options available (deferred payments etc).
If Netjets looks good for you, and you think you're up to the rather high mark, then get yourself up to OAA pronto!
