I would say...pretty much as good as, and pretty much the same price, used.
Haven't seen any complete NIB groups of NR around lately, but have seen a VERY few DA ones, priced around $800.
Which, I think, would be about the same for a similar NIB NR set.
Last very, very nice (but not new) complete- less hubs and pedals- NR group I sold was around $550.
But, ultimately, for a bike I'd actually ride for enjoyment, I'd either go later SR, maybe '83 cuz it shifts a 28 big cog, or DA 740X.
That stuff just plain works better.
