I know you said no twin boom but it's hard to beat a bobcat xl. Much better jet than the falcon 120 and I've seen them well under 2k rtf less turbine. In fact i paid less than 2k for mine. I also paid under 2k for my CAI raptor, bvm kingcat, a reaction 54 that was turnkey with pst600, and just picked up an old skymaster F15 for 800 bucks (Canadian).

I've seen the original flash in your price range but honestly if I were you I'd just finish you f16 and fly it. Keep it light to start. No smoke or extras. Many in the jet world cut their teeth with the 1/8 F16's. They area very easy good flying jet.
