You picked out four very nice cameras.
The Canon SD500 has been replaced by the SD550.
Here is a look at their specifications:

Only the Casio Z750 has manual controls (Shutter Priority, Aperture Priority, Program, Manual).
All of the cameras have been rated high by their owners. You can't go wrong here.
Go to a camera store and get you hands on each camera. People usually prefer the feel of some over the others.

hello,
i am a young, yet pretty advanced photographer. I need a new high-megapixel (6-8 megs) or ultra compact camera for spring break and college. I have looked at the Nikon 7900, Canon sd500, Casio Exilim EX-Z750, and the Panasonic FX9k. I have really have liked using nikon cameras over the years, but is the Nikon 7900 really worth the $(b/c it doesnt have a 2.5" screen or manual controls?) Are the big brands like nikon and canon worth it, or should i go with my instinct and buy the casio? Well, here are my wants/needs:
-must be aesthetically pleasing (looks nice)
-must be small, yet somewhat rugged and last for a few years
-must have manual or decent semi-manual controls
-must have 3.0X or more zoom
-must have 2.0" or bigger lcd
-must have great image quality, esp for portrait and outdoor photography
-wi-fi does not really matter, nor does a view-finder, considering most view-finders in cameras this size dont do anything
please help me if you can; im running out of time and cannot make a decision.
