Hi - I'm looking into buying my first digital SLR. Does anyone have any tips or recommendations? I've been researching different brands and models for awhile, but there just seems to be a massive wealth of information. I'll likely be doing more outdoor shots than indoor, and I'd prefer to spend a maximum of $700, although less is always better. I've seen the Nikon D40 for pretty cheap (~$420). Or the Canon Rebel XS (~$499). Does anyone have any strong objections to these models or can offer some insight as to which is better? Or maybe they are both bad? Thanks for your help!
