F-86, how about the Cermark F16 with a wren supersport? What kind of planes are you comfortable with flying right now? Anything fast? A baby boomerang would be good too. There is nothing cost effective or cheap about the jet hobby period. Dollar for dollar there are other places to find entertainment if cheap is the requirement. But it is quite fun and that is all I'm in it for. Good luck with your choice, there are many roads to the right first jet but it is littered with shills and reps. Get the one you like.
