Which Lenovo S'series smartphone is best?

I'm looking for a unlocked smartphone under $250. My requirement is good camera, big screen, and long battery. I know its difficult to get all this features with this budget. So after long research I'm finding lenovo smartphones with this budget. So anybody can suggest me which lenovo smartphone is best or any other options are also welcome.

You should check out the Lenovo S660, it's quite good I must say. It got a 3000 mAh very very huge battery along with brushed metal body, quad core processor.
