I just want to comment here, I think one of the main things with progression to the second plane has to do with the thought of "it's an ugly trainer". Now, I have very little stick time yet, I have the LT-40 and a Sig Senior Kadet ARF (Which I consider to be one of the better looking trainers). Of course I want to move on to a Venture 60, but why rush it? It's alot of money to watch fly into the ground.

But overall, I think people want to progress quicker because they want to get a plane that is nicer looking. I really like the Cessna's. and I ogle them in the catalogs all the time, then I load up my Realflight, switch from the trainer (that I can fly pretty good), to a low wing intermediate, think of it as my next Venture or Cessna, plow it into the ground because I don;t know how to accuratly handle yet, and realize, "yup, back to the trainer"
