One more vote for the Sig 4-star. I was never crazy about the way this plane looked, but after hearing for years about what a great flier it is I broke down and built two of them (one for me and one for my flying buddy). I will always have one of these planes in my hangar now. This is the smoothest flying plane I have ever flown. My buddy and I joke that we feel like we're cheating when we fly it because it makes us look like better pilots than we really are. The construction is only slightly more involved than a trainer, and with a few easy modifications it can come out looking pretty sharp. This is an ideal second plane.
