I am in Phoenix. I can definitely offer some suggestions. First of all, when are you coming out? Where in the Valley are you going to be? Scottsdale has the most upscale courses in the closest proximity to one another. Obviously, this is going to be the most expensive area to play. If you don't mind traveling, I would recommend WeKoPa (Cholla course over Saguaro), Southern Dunes (one of my favorites in the state but a bit of a drive depending on where you are), Papago (a City of Phoenix course that is in great shape and it is 7000+ from the tips), and Quintero (another one that is a bit of a drive. I haven't played it but it is on my short list and I have heard raving reviews).
Let me know where in the Valley you will be staying and I will offer more suggestions if you would like. Also, check golfnow.com for the best deals in town.
