Best way to cook a generic non-carrier-specific Touch ROM?

[UndeadSquirrel]

I'm thinking I might sell my Touch, but only if I can get a good amount of money for it, since I'm really hurting for money and can't even afford my Cricket bill now. So I figured it'd be easier for whoever buys it if I can cook a non-carrier specific ROM and throw in the carrier cabs for them to install. Should be a cinch, right? What's the best way to cook a "generic" ROM?
