RiverRat:From what I've heard more MP is not always better. CCD quality has much to do with image quality as well. If I understand it correctly you could have a 5 MP camera with a great CCD or a 10 MP with a crappy CCD. I guess the best option would be the 10 MP camera with the great CCD.
I've never seen a *crappy* 10mpix sensor.

Keep in mind that there are a handful of sensor manufactures, and you will find Sony CCD's in camera's made by a dozen manufactures.
The manufacture process of the sensor, CCD, or CMOS, has unbelievable quality control, and a very high reject rate.
Even Canon who makes it's own CMOS sensors for DSLR's uses sensors made by manufacture *unknown* in most of the PnS models.
When someone says that camera A has a good 5mpix sensor, and camera B's 8mpix sensor is not so good, what they are most likely not understanding is that other factors have impacted the image quality. More mpix does have the negative impact of potentially more noise as the photosites become smaller.
If you want to make constructive comparisons, look at the "compared to" sections of Phil's reviews. Open two windows, and look at a 3mpix resolution chart image compared to that of an 8mpix camera. The difference is rather pronounced.
The final decision is based on what you are going to do with the image. If 8x10's is the goal, sure a 5mpix camera is likley all that is needed.
