Best water pump to get?

I've got a '09 IS350 with a water pump going out, leaking a steady stream of coolant. I was looking on rock auto, and there's a range of $40-$90 pumps. AISIN is the most expensive one, but says they're Japanese manufactured and would be the OEM replacement. Does that hold any water? If not which one would be the OEM replacement? I appreciate any help.

Edit: No pun intended, lol.
