Got one 3 months ago. For the record, it cost $2500.00 a year and you need to charge $150,000 in a year to get the "invitation" from Amex Centurion.
I hope it is worth it. So far, the personal travel consultant and conceirge have been excellent in getting me upgrades and "hard to get" reservations at top restaurants and shows. This alone may be great value to some people.
