Hello everyone...newbee here...from Canada(eh). I'm looking for a used 4,and need advice. Is a 1050 classic 4 worth the same as a 1200? If a KF is well maintained, is 500 hrs total time alot?what is alot? Is a KF from the early 1990's still a good plane or have there been upgrades that make something around 2005 better? How do I buy one when I'm 20 hrs. away(by car) and will need to buy sight unseen? And last(for now), do people sell these at Oshkosh? Thanks, Dan
