Hi i'm using an Powershot A75. But i reccommend A85. Cos the LCD can swivel one. Then it also has manual mode for you to learn. I'm using budget camera so i only have enought to buy A75.
Furthermore you can buy tele or wide converter and fix on ur cam. Cool. Should try it. A80 or A85 i think if you not familiar with wat exposure, composition, or flash or shutter speed that kinda stuff.
But the Powershot doesn't look as suave as ixus. *sad*. But who needs style when u have quality.?
