Help choose my new camera...

[oroboros]

Hi everyone, great forum here. I'm going to be buying a camera soon and while I'd like to step up to a nice Nikon or Canon SLR, my budget won't allow it at this time.

So I need something cheap with nice image quality, useful manual control, good lens, ect... All at a point & shoot price-hopefully. My budget is between $150-250.

I shoot a lot of outdoor landscape, macro shots, and wildlife. Also I like to shoot at night or in low light conditions at times.

I've been researching for awhile online and have narrowed it down to a few models, so if anyone has any advice or opinions on the pros & cons of any of these or even something not on the list I'd be thankful. Take care.

Canon
PowerShot SX100IS
PowerShot A720IS
PowerShot SD750 / SD1000
PowerShot A590IS / A570IS

Nikon
Coolpix P5100 / P5000
Coolpix P50
