When I saw photoshop I thought you were talking about Photoshop 7 or CS. Had to check out what Digital Image was and then determined by your comment on the price that you must have been talking about Photoshop Elements. I would go with Photoshop Elements personally;-)
elements is really meant for amateur photographers to tweak there images and for the money is a bargain but isnt really the creative tool it's big brother is. Full blown Photoshop is still pretty much peerless and the latest incarnation - CS - is a quite significant and welcome upgrade.
