After being a member of Yeamans Hall for quite a while, my job relocated me to Jacksonville. I asked a friend of mine in the business the best deal in town, and he pointed me to joining the Valley course at TPC. I've been out there a little over a year.
As far as the Stadium course, the market determines how much it will bear. I won't pay $400 to play the Stadium, at least I don't think I would, but every time I'm at the driving range getting ready to play, there are plenty of people out there fired up and ready to tackle the Stadium.
There are other things to consider. I played Pebble once, and I really had a hard time forking over $400, but it was worth it to me for one time. I am glad I did it. Another thing to consider is the price per round for your own home course. If you play on a course that charges you a one time fee at the beginning of the year, take that and divide it by how many times you play that year. Some people, it's a steal, some others, if they play once a month, it could run over $400.
TPC Sawgrass is a great operation. The people out there are extremely knowledgeable and pleasant about what they are doing.
