Hi all, I'm looking to by a flashgun for my Nikon D5000 but as a total noob I am unsure what things I need to take into account when choosing one other than budget of course.

I deally I'd like one with tilt and swivel and preferably an inbuilt diffuser if such a ting exists?

Budget of up to £150 or thereabouts.

Thanks in advance.
