For some reason i don't want to spend much on a flash. But, i have come to the conclusion that i need at least a 430 ex for my 50d. $399 on DD-photographics (on-line), $429 from CameraHouse, do i need to spend this much?

Can anyone give me a few pointers on what i should look at. I would use the flash for family stuff, macro at times and not sure about birding though. As per usual I would look into learning more on how to use it etc.

I went into Perth - PRA imaging was closed . A couple of other shop assistants were not very helpful at the camera shops. One guy just said we don't have them, you have to go somewhere else. I asked them about the Sigma flashes EF-530dg super.

I came away with Scott Kelby Book "The Digital Photography book - vol 2". I am back to saving a bit more money and talking my husband into letting me go a bit more money.
