G'day guys,

Very lost in looking for what I need or should be buying.

I am looking a buying a flash for my D90 as it seems a necessary buy to improve on my low light/ indoors photography rather than using the pop up flash. (I tend to get a shadow from the lens using the pop up).

As the Nikon branded flashes are quite expensive (im on a budget being a beginner), does anyone have any suggestions on a relatively good generic flash for my D90?

I have had a bit of a look on ebay at brands such as Vivitar & Nissin but am totally unsure of these brands or what I should be buying for flash photography as I am new to it.

Any help will be much appreciated.

Thanks.
