I was in the same situation as you not too long ago, I went ahead and got me a Sig 4 star 60 low wing really cool airplane, I build the 40 version and the 60 both kit and ARF a few years ago and I knew that airplane will do it for me, it is now on floats too.
If you want to go a little more agressive check out the Great Planes Revolver 40 or 60 both are really good ARF, I have the 60 with a ST 90, this is a really cool ( again

) an all around sport airplane has features like the big gasser top hach, 2 piece wing with a carbon fiber tube, very large Rudder, Ailerons and elevator ( it is not mented for 3D not my flying style anyways ).
