Here's a headset you might consider that's a great bargain:

Miche Primato needle bearing headset.
Pretty much a copy of Stronglight's needle bearing headsets, but without the sticker shock.
I've seen these for sale at eBay, brand new, at around 45 bucks average, which is easily half of what equivalent NOS Stronglights sell for.
IIRC, the headset also has a lower stack height than most, so it can handle steerer tubes that were cut a bit short.
I have it on one of my bikes, installed about three years ago, and it had performed just as good as my A9's so far. I think its design will also look at home on most 90's bikes with 1" threaded steerers.
