Canon Cameras

What is the difference between these two canon cameras?

Canon PowerShot A550 7.1MP Digital Camera with 4x Optical Zoom Canon PowerShot A570IS 7.1MP Digital Camera with 4x Optical Image Stabilized Zoom they both have 7.1mp and 4x optical zoom except the a570 has image stabilized zoom so is that the only difference? i'm trying to figure out if that's the only thing because that one is $20 more. thanks!

1. Looks like the A570IS Has A bigger LCD Display (2.5" vs. 2"), Supports up-to ISO 1600, Has 7 more Scene Modes, and Weighs a bit more, but is smaller in size than the A550. Biggest reason to get the A570 over the A550 is the image stabilization. Especially with extended zoom, where camera shake is more noticeable. For $20, nothing to think about. Go with the A570 IS.
2. You consider that the A670 IS has both aperture and shutter priority modes, it is a steal for just $20 more ... add the IS, one stop more ISO range and the larger LCD are worth much more than $20
3. get the one with the sttabilized zoom it makes piter takeing much easyer there is not much more fusterating when try ing to take a picter and it comeing out blurry because u cant keep the camra still unof and it gets even harder when u zoom to do that so they have that feater of stabilized zoom to help u and it is difently worth it
