Photography Frames

What would be a good DSLR camera for nature photography?
I have been using compact cameras for a couple years and I want to step it up a notch. What would be a good DSLR camera to look into for nature photography? I need something that snaps fast. Someone mentioned something along the canon rebel line but I don't know. Also, should I consider a camera with Full Frame capabilities or is that just a little overboard? Thanks!
You really want a crop sensor for wildlife. The crop brings the animal in closer, effectively increasing focal length.
I shoot Nikon, so my recommendations would be the D90 or D300s. It depends on budget, the D90 is around 750.00, and the D300s around 1500.00. They both have same sensor, the D300s has a higher frame rate and more metal in the body.
The lenses are the part where you need to spend the extra money. You need a 300mm lens at a minimum for wildlife, and an 11 or 12mm (cropped frame) at the wide end for scenic shots. Tokina lenses are really good glass, and a lot cheaper. Look for the 12-24 or the 11-16 for wide angle. For telephoto the 100-300 F4 is really good. They also make a really good 28-80mm 2.8 to look at.
The best approach would be to buy a D90, and have extra money for good glass.
Both of these shots were with the D300, the D90 has a slightly better sensor.
Here's a shot with the 100-300:
