OMP if you want a ARF, Swanys House if you want a Kit. I think OMP still has some kits also. Can't go wrong with either one. They both have planes that will fit just about any engine size. I currently have the OMPYak with an OS55AX Excellent combo. Yak is similar to the edge. The edge will be a little more stable if you are just starting to learn 3D, but still a very capable 3D plane.
