I've had Funtana and have the Synergy 90 3D now. They are not in the same league! While both can do 3D, the skill level to do 3D with the Synergy 90 is higher - and so is the quality ($170 vs almost $600). The Synergy has a very thin airfoil so don't expect it to fly as slowly as the Funtana.
You can read many differing opinions on the Funtana but I just wanted to pass along the thread for the Synergy 90 3D.
Let us know what you decide.
