are you going to be using Minolta as a long term solution? if you are, get the 5600HS (D). can be used even when u upgrade to 5D or 7D, or maybe future 9D
I dont suggest Minolta as a long term solution, perhaps you may want to invest in the Metz 54 MZ-4, a great flash, so that when you upgrade your camera to a canon or nikon you can still use it.
