Has anyone used a Canon SD450? If so .... what were your impressions / thoughts? I'm currently looking to get a small point and shoot camera without spending $500+. Right now my frontrunner is the SD450 with a second battery and gig memory card. My major requirements that the camera be: Small and light - has to fit in a pocket while I'm carrying other gear Easy to use - I want to be able to whip it out and take a snapshot at will Reliable - same as above Robust - needs to live in my jacket breast pocket happily I've been pretty impressed with Canon's offerings, my brother and father both have Canon ... A520's IIRC. Both of them are very happy with the Canon software / interface / etc. Any advice would be greatly appreciated, thanks.
