KRAM you are not correct regarding an individual not needing any training at all. Virtually no one without the qualifications or training could disengage an a/c auto-pilot and sucessfully fly it anywhere. This can be demonstated quite easily in a simulator. Sky clear at 10000 feet and 9 out of 10 people will have it buried in the deck with a few minutes.
If you do not require the endorsement for work purposes, I would imagine it is now impossible to get any type of transport jet rating. I certainly do not begrudge you the opportunity, it's just the way it is these days.
B737 is a fine a/c!
