Also look at www(dot)megapixel(dot)net - a Canadian site with good camera reviews. Be careful with warranties - some camera companies will only honour the warranty in the country of purchase - this can be a hassle if you are not on the border like I am. Canon honours the warranty of cameras purchased North America-wide, so no problems if you have an issue. Definitely something to look into and ask about.
BTW, I use a Canon SD800, Sony DSC-H1(with the dreaded shutter switch failure!
, and my new toy on the way, an Olympus 510 DSLR.
