Lisa,
I am also in the debating stages of purchasing a digital camera. This may be a little off topic, but something to consider when paying the large difference say between a 3 Mpixel or a 5 Mpixel camera is the following. The following calculations below assume a 16" x 12" image in Photoshop.
A 3.15 Mpixel camera, producing a max. resolution of 2048 x 1536, will yield a 128 dpi image.
A 3.87 Mpixel camera, producing a max. resolution of 2272 x 1704, will yield a 142 dpi image.
A 4.92 Mpixel camera, producing a max. resolution of 2560 x 1920, will yield a 160 dpi image.
Looking at the dpi, there's not a huge difference in resolution between say a 4 Mpixel camera and a 5 Mpixel camera. You can do the calculations for any size image you're used to working with, but the increase in dpi is misleadingly small compared to the increase in price as you increase the Mpixels.
