Which one is the best?

[sciencekid]

Hi,

I am a noob at digital immaging and I want to start making great pictures(most of all nature pics, landscapes etc.) but my budget isn't very high +/- 450$

What I wanted to ask is which one of these 3 cameras are the best (best image quality, fast shutter,....):

- Konika Minolta DiMAGE Z2
- Fuji S5100
- Kodak DX6490

If you go by size, picture quality, speed, optical zoom, and price I think the Penatx Optio 555 is one of, if not the best out there. Small camera with a 5x optical at 5mp.

size doesn't really matter to me, but I like SLR-designed cameras :p
