I remember those USCF Jaques knockoffs (of the Fischer-Spasskys set to be precise) and the work was pretty slipshod, but back in the early 80s when it came out there were virtually no alternatives in terms of ebony sets.
Nowadays you can find what you want, basically. I guess no ebony for the Grandmaster from HOS so far--but this can change .
For $70 to $90 US (full retail) ...! Twenty years ago, you'd have a hard time buying half the set at twice the price!
That's the exact chess set that I have, and I wouldn't go any higher pricewise. All of HOS's chess sets are fantastic, even the inexpensive ones.
EDIT: That would be this one, in boxwood/ebonized boxwood.
