Cristal is for rappers and wanna be celebs. Of course, if I made $10,000,000 an album (it took 50 Cent only 45 minutes of work on his first), I might be more inclined to splurge myself...
Moet & Chandon have a Napa Valley version, good value for the price. Also if your wallet is feeling the pressure from pooning, try Seaview it's a product of Australia - good stuff.
