Having worked on the F-16 in my first job (Jovial runtime libraries) I have a real affinity for it. Even today you can buy a whole boatload of F16s for the cost of 1 F35. I think the plane is too expensive to use as an everyday FB.
Not sure about a boatload. Current build (Block 60) Vipers are close to $100m depending on how you calculate the cost of spares etc. It'll be interesting to see how much the UAE pays for the Block 61s they requested this year.
