Speedflash or flash gun

[JBenCPhotography]

Just a quick question...
What's the best flash gun on speed flash to use in a night club or for low light photography.. I'm using a Nikon D3100 and really need some positive advice seen as I need to have one by Saturday night,
Thank you

For your camera, probably the Nikon Speedlight SB-900.
Maybe something like this...Product information: Metz

The Sb900 is Nikon's most powerful speed light. Most likely the best thing you could buy for what you need.

Around how much will this cost me?
