I have an Epson 850z
It goes to 1.9 MP.
I normally take pictures at 1600x1200 which is close to the 1.5 MP range.
For showing pictures to people that particular size will be fine. It's when you go to print those images that the higher rsolutions really pay off in quality.
It really depends on what you want to do with it.
The pic's in my sig were all taken with that Epson.
They have been reduced on that site for download times , but you can see they all turned out pretty well.
