I disagree. That may be true about that being the year that all prices jumped up, (probably related to the "Tiger effect") but since then they have hardly changed. Top of the line drivers are still 400 (a lot of nice ones are 300), irons have been in the 600-900 range forever. Heck, in the 90's when Big Bertha's were all the rage, those things were 1000+ if you wanted graphite shafts. Titleist professionals were over 40 then, prov1's over 40 now.
Greens fees may be a little higher now than then, but by and large, costs are what they've been for a long time, even with all of the advancements in technology.
I agree with the rebuttal, and will add that the Callaway clubs (metal woods specifically, with the Big Bertha) were some of the first to make the price jump.
