If you like your tracer, and your friend is not a builder, I would recommend the GP Ultra Sport 40 ARF. Although I usually steer people away from BARF's, the Ultra Sport is by far the best 40 size plane I have ever flown, and it is no longer available in kit form. GP claimes that the Tracer is the replacement for the US40, but I have flown two of them, and I don't think it even comes close.
