Hey everyone, I recently bought the canon a590 and am pleased with it. However, I just got my tax return, so I'd like to upgrade. The two models I'm looking at right now are the canon a650 and the canon sx100 IS. Why I like the a650: 12 MP resolution, flip out LCD, viewfinder. Why I like the sx100: bigger sensor, 10x zoom, instantaneous shutter, apparently better in low light. I'm leaning towards the sx100, but I'd like your opinions. What do you think of these cameras (including the a590 as well)? Which should I buy? My main wants are image quality and shutter speed. I'm no expert, but from what I've read, a bigger sensor gets you better image quality because it produces less noise. Is this right? I don't know what will give me better images - a big sensor or a big resolution.
