Nexstar is the "best" because it comes with simulator, and its the newest thing, and you also get your plane replaced under certain circumstances if you crash it, but its got the worst price

. A list of good trainers which seem to have been approved by RCU is:
Hangar Nine ARROW (aerobatic = tricks)
Hangar Nine ALPHA
Superstar
Nexstar
Sig LT 40
I've got the Alpha because it was my 2nd choice and i got a deal on EBAY. I would recommend getting the ARROW brand new (only $259).
