"all entry level cameras are pretty good. dont be fooled into only nikon or canon. yes they're both good, but so are the others. try them all. at $500 starting point for most entry level kits, they all perform pretty much the same."
Yes and no.
While other brands definitely have good gear - it's important to remember when you buy a camera you are buying into the SYSTEM rather than just the initial purchase of a camera and single lens.
Lenses are expensive and once you get the good glass fetish changing systems becomes a VERY expensive proposition indeed.
Nikon and Canon have the best systems out there IMHO.
Also you can rent lenses for special trips that you'd never consider buying - I hauled a $6500 500mm f4 IS to Africa - I rented it for ~= $500 for a 3 week trip.
Most of the rental places will carry both Nikon and Canon - but try finding a Minolta or a Sony rental....
I'm not knocking the quality of the other manufacturers - just pointing out that you should consider the overall system rather than just the bits you buy initially.
The suggestion of looking at something like a Canon G10 is an excellent suggestion if budget is tight - I have one that I carry when I get the "This is not a photo trip" speech from

. It's very flexible and has full manual control that lets you do everything a DSLR will do except switch lenses. Which isn't that big of a problem as the lens on it is excellent.
Images from the my G10 can be every bit the equal of images from my 5D with L glass on it - I know of quite a few pro nature shooters that are selling images from the G10 and they print very well indeed.
It's got a way to go to compete with my 4X5 sheets from my Ebony for pure detail though
