I'm looking to buy a digital camera. I'm really just looking for something to use for snapshots and to take on vacations and things like that, so I'm not always lugging around my Nikon N80. I really don't want to spend more than $400. Does anyone have any advice on brands and models I should look at? I've been looking into Nikon and Olympus but I want to see if anyone can recommend anything specific. Thanks.
