Well built airframe
I would take a well built kit (airframe) that has not seen much use over a substandard constructed junker that has had the wings flown off. You can always upgrade and improve the systems but upgrading poor airframe workmanship is not so easy. It also depends on your interest in learning about the systems and making improvements yourself. If you don't like that sort of thing than you should do what all the "How to buy a used airplane" books say. That is; buy an airplane that has already been upgraded.
OK, I'll get down off my apple crate for the weekend.
