We are starting a new campaign, and the DM wants to keep down the number of books needed without reducing options too much. He wants to avoid cherry-picking from twenty books. One suggestion is to limit characters to the PHB and one suppliment, but that doesn't allow for things like psionic prestige classes from the Races books, and the warlock feats in Complete Mage. So maybe PHB and two suppliments?
How do other people handle this?
