I am one of the instructors in our club. Most of the trainers I have flown is the Avistar, Tower 60 trainer, Supper Star and even a duraplane. We recommend the Avistar to beginners in our club because it is a very nice aircraft and you can use it for basic aerobatics.
One of our students got a nexstar I started training him on it about two months ago. This is the worst plain I ever flew. If he ever gets a second plane he will half to get help because it will fly anything like the nextar.
It is even worst than a duraplane. But it looks good.
