that's probably true. I see 4 in the FAA registry. I don't see any MiG 25s but I see 5 MiG 29s in the FAA's US registry.

Even the MiG 29 would get you marginally better Mach numbers (2.2 vs 2.0) and better payload. Plus they were produced in similar numbers as the F104.

A MiG 29 is still on the trailing edge of what's considered state of the art for fighter aircraft. It's essentially Russia's version of the F-16/ F-18. I would imagine that mid-century F-104's would be much more affordable.
