HELP!! i need help buying a new digital camera!

any advice would be much appreciated. of the specifications, the more important ones include:

size- preferably ultra-compact, thinner than 1 in.
image quality- not stellar but good clarity, no fringing
flash- able to highlight to decent distances
features- a few good scene modes
brand- preferable reputable
price- somewhere from 250 to 350 (flexible for quality)

of the cameras currently out, i have looked at:

canon powershot sd450 (or sd400)
sony cybershot (various dsc models: L1, p200, t1, t33)
kodak easyshare v550

again, if anyone could point me in the right direction, i would be very grateful!
