Flashguns for my Nikon D70?

I'm looking for a flashgun for my SLR Nikon D70.

I need a wireless flashgun and can be compatible with the Nikon D70

Please note that it is the D70, not the D70s.

Are there any out there at a reasonable price, or could I get a bog standard flashgun made by Jessops and get an adaptor. I know nothing about Flashguns but my photography tells me I need one. Any answers. I will give out best answer so points could be earned.

What is it about your photography that tells you, you need an electronic flash?

Are you starting to shoot more events?

The best one would be the Nikon SB700, unless you can find a good used SB600.

The SB700, while better than what you need now, will take you into your next Nikon dSLR camera in a few years.

You need almost any flash with a slave adaptor. This will fire the flash as it sees the on camera flash. Don't bother with wireless systems till you have learnt a bit as they are £££££
