I love Second plane threads - because I remember how much fun I had flying my second plane after I was 'finished' with my trainer.
I got the Phoenix Dolphin. It was a great value at about $99 (well I guess it went up a few bucks) and felt really sporty. You even get a lumberjack for a pilot, which is fairly comical.
