I've heard that all of the above mentioned are good. The only ones I have actually built are the Great Planes PT-40, and the Goldberg Eagle, and I would recommend either. Although, if you build the PT-40, it has two wing diheadral options, build the one that uses less even though they say the one with less is for more "advanced" flying, IMHO, the "beginner" wing has too much dihedral.

Which ever you get, I'm glad to see that you plan on building a kit instead of buying an ARF. Trainers are easier to build that the planes you will be flying later, so you need to start aquiring those building skills now!
