Looking for 12VDC Powerhead/ Small Pump

[Qwiv]

I am going to start working on a project that will require a powerhead or small pump to be run from 12 volt DC. Can't use something huge like a Tunze, as it will be similar to a Nano. IT also needs to be small, think Nano Tank.

I found a pump that computer overclockers use. Emailed the manufacturer to see if it was salt water safe.

Any other suggestions.
