RE: Best 3D foamie to buy.
You could pick up the Yak 55 or McFoamy from WM Parkflyers.

Or you could pick up the Yak 55, Sbach 342 or Edge 540 from e-foamy.

All of these planes have a good reputation. I fly an Edge 540 and a 42" Yak built from the plans and I'm waiting for the electics for a 32" Yak 55 I've got built.
