I am looking at the Nikon Coolpix 2100 for $199.99. there is a review here http://www.imaging-resource.com/PRODS/CP2100/CP21A.HTM This camera doesn't seem to have a viewfinder (other than the lcd screen). Is this a disadvantage in sunny locations and will this cause the batteries to wear down faster? Does anyone have this camera? Any comments appreciated. Bob
