The Senior Kadet is much stronger than it looks. We use a kit built Kadet to let newbes fly and to just have fun with at the end of the day. It is on its third or fourth engine and still going strong.
One plane not mentioned is the new Hobbico 60 which has a semi-symetrical wing and mono-coat covering. I have a new one in the box I could make you a deal on if you lived closer.
