In 1/48th scale you've got a pretty good selection of choices:
Tamiya - altho, IIRC this is "sort of" the YF-16
Hasegawa - A/B/C/D and different blocks therein, general consensus seems to be the Hasegawa kits are the best of the lot
Academy - A and C, I really like these kits and (for me) are a good alternative to the more expensive Hasegawa kits
Testors/Italeri - IIRC their F-16 kit (primarily an early A model) allow you to do either a single-seater or two-seater.
Heller - I think it's a re-pop of the Testors-Italeri kit
ESCI - A model, fro a variety of reasons, I'd pass on this one
Monogram - Did a "sort of" YF-16, too, then later marketed it as an F-16A.
Revell - a "ditto" of the comments for the Monogram ki
