Hi

I'm new to the world of SLRs, but have the option to get one of the following. Are these good options, in particular for beginners?

The reason I'm getting this camera is for use whilst travelling south america (wildlife and landscape shots in particular).

- Nikon P100 10MP Camera
- Sony A290 14MP DSLR With 18 to 55 Lens
- Nikon D3000 10.2MP DSLR Camera with 18-55mm Lens
- Canon EOS 1000D 10MP Digital SLR Camera with 18-55mm Lens.
- Sony A390 DSLR Camera with 18 to 55 Lens
- Pentax KX 12MP DSLR With 18 - 55mm Lens

Many thanks
Mark
