DuraAce cones are at DA prices for a reason, but if you're a cheapskate count the number and size of balls an get a low-end Shimano cone which uses the same balls.
Which is because people think that a marginal improvement in quality warrants a huge increase in price. I once foolishly ordered DA chainring bolts, £42 a set! Even the QR springs were £7 each!
And of course they aren' a lot better, otherwise they wouldn't have pitted just the same as cheap ones do.
Many shimano cones are interchangeable, so it should be easy to get some usable spares but they have to be pretty mangled to noticeably affect the performance of the wheel, clean them up, apply lots of fresh grease and new balls, and adjust very carefully. They should be fine.
