I am stewing between the two. This is my first DSLR camera after using point and shoots all my life. I like the Canons for sure. The XS is less in price by fifty bucks and is brand new carrying a 1-year Canon warranty. http://www.adorama.com/ICADRXSKB.html?searchinfo=canon xs&item_no=1 The XSi is a refurb from Adorama and carries a 90-day Adorama (not Canon) warranty. http://www.adorama.com/ICADRXSIBKR.html The XS probably suits my needs, I guess, but the XSi has higher megapixels (12 vs 10), more focus points (9 vs 7) and a few other key upgrades. A new XSi is way outta budget. Just a little concerned that it's a refurb I guess. Otherwise, it seems to be worthwhile to throw down the extra $50, right? Please vote!
