I need a cheap SLR-like camera, what is your suggestion?

I'm used to do photography with a Nikon d80 camera, with 18-55 and 70-300 3.5, 6. But I have lost this camera and lenses. I want to buy a new camera in budget. I can dedicate 500$ at maximum for purchasing a camera an it's lens.actually I know that it is not that much, but at the moment I can't cost much more. On the other hand, I can't live without the camera, I'm addicted to do photography. One day I decide to not purchase a camera until I would have a budget of 2000 to 3000 dollar. But this can't happen soon.

Anyway, I decide to but a camera for landscape, outdoor, nature. I'm serious photographer who detail and sharpness is much important for me. I recently found Canon hx50 interesting while cannon G1x catch my eye because of 24-1200 lens capability and big sensor respectively.

I'm not sure if these camera can meet my demand.

What is your suggestion?

Price Low to high.

NIKON D3100 Digital SLR Camera
CANON EOS 1100D Digital SLR Camera
NIKON D3100 Digital SLR Camera with AF-S DX 18-55 mm VR Zoom Lens
NIKON D3200 Digital SLR Camera

Get the Nikon D3100 or the D3200.
Stay clear of Canon. They are horrible!
I had 4 Canon cameras die on me.
I treated the cameras really well.
Get Nikon and you will be happy.

I agree, Nikon D3100 is a great option.

Not a problem, you can get the Nikon D5100 with kit lens inside that budget.
If you actually need a long focal length at this time then you won't go wrong with the Canon SX50 if you support it on a tripod, monopod or Gorillapod. Apply the same DSLR skills to using this small sensor camera and keep ISO low, and you should be happy for quite some time with it.
