City is a bad move. Licensed sets, Ideas, and modular Creator sets are better bets. You're really looking of uncommon pieces in rare colors or unique minifigures. The radar dish from the original UCS Millennium Falcon will fetch a couple hundred dollars because it's a custom print. There's an X-Men set "Wolverine Chopper Attack" or something that retailed for $20 but goes for about $60 on the secondary market because it's the only set with a Deadpool minifigure.
