Could you recommend DC mini-series?

Recently someone recommended me 'Lex Luthor: Man of Steel' and I loved it. Hadn't heard about it before, though. So my question is: does anyone know some good comic books that are not very well known, preferably mini-series or one-shots. From time to time I find gems like that and I'm in need of another one.

Thanks
