Someone in the family wants to get me a camera. Preferably from Costco.

I spend most time in the redwoods and other forest. Am fairly novice, but would like a camera from which I could get a few shots worth selling someday. Whether for posters, mugs, etc., after I improve.

Was looking at the Nikon D90 and a Canon Rebel EOS T2i

Wouldn't mind one with two lenses, like a T1i on page 2 of the Canon.

Here's the main Camera page to navigate to either Canon or Nikon:

Now ... speed is not a huge issue for me. I don't care if a camera takes one frame in 2 seconds. But the quality is what I really am curious about.

Feelings? Ideas?

Thanks
