Hi I have a 450d and currently only the pop up flash. I am looking for a flash to enable better indoor and night shots and really like the look of the 270ex as it is compact. The cost however is about the same as the 430ex which seems to be over spec for current needs but at least the option is there if I need it. It does however look a lot larger and imposing than the 270ex. Any views on the best way to go appreciated.
