Which Camera To Buy

[willbemcse]

I am looking for a camera with atleast 4.0 and atleast 4X or better zoom. I looked at these camera

a)Kodak DX 6490 has a good lens , good zoom .

b) Canon 1IS has IS but its only 3.2 and has a small LCD.

c)Kodak DX 7440

I will be taking variety of shots some night, some day , indoors, closeups. Which of these camers have low purple fringing , low noise. I am also looking to buy a camcoder to take night shots or in low lights any sugestions on that. I looked at Canon ZR90.

Thanks :-)
