These sorts of value propositions are hard to answer, because it depends on the individual. $450 is over the moon for some guys, but probably a small number compared to taking your family to Argentina.
The Red course is a 6 on the Doak Scale.
Generally, courses in Argentina are not maintained to the same ridiculous standards as in the USA. He's not likely to find greens running at 11.5 on the Stimpmeter anywhere in South America. If "well maintained" is a big part of his priorities, he should probably leave his clubs at home.
It's a great club, and if you had the chance to play with a member and get a feel for the place, then it might be worth it. [I also highly doubt it would cost $450, which ought to go a long way in B.A. at the current exchange rate.] But, $450 to be shuffled in and out by a tour operator? Probably not worth it, unless you are a huge fan of Dr. MacKenzie's work, and/or you haven't been able to see much of MacKenzie's work because so many of his best courses are private.
