Bob - very touchy subject for me here, as I have the reputation as America's Guest (2nd to Cirba!
) and I live in amazement and gratitude.
In any case, I believe young Todd hit the nail on the head here - if one receives an invite to Cypress, for example, "how much is it gonna cost" is about #1000 on the 1000 list of thoughts that race through one's head. Your quote was nearly exactly what I paid (I think), and I never thought of that at all until right now - and I may even have it wrong as I write this today.
John F. nailed this also. The price is completely secondary to the memories one receives from a round at the great clubs like this. I'm just like John F - I can live forever off the memories of my tee shot on 16 Cypress. The fact some damn cool people were there to share it made it all the better....
I know this doesn't answer Ian's seemingly simple question. But places like Cypress, Pine Valley, etc. are just such a treat, it's really hard to quantify. One's financial status factors into this greatly also... Let's just say for me, I'd pay any amount that my wife would allow without castrating me. And luckily, she has a very good sense of the importance of golf in my life!
