Since you didnt mention the Kadet LT 40, I won't either. But amongst your options you listed. The Nextstar, by what I have seen is a great set-up. With the included Simulator and added train-eze attachments, its a smooth startout trainer, then the "aids" can be removed when the pilot is comfortable with it, and it behaves more like a sport plane.
Course theres always the Kadet LT40. (oops! mentioned it.)
