I'm not sure which of these Digital SLR's to buy. I've always owned Canon products, but believe Nikon may be better. I'm trying to choose my first Digital SLR. It's between the Canon EOS Rebel XTi and the Nikon D40x. If both are priced the same, and they are at www.bestpricedcameras.com for $449.00, which is the better choice. The kicker for me is all the Sigma Lens's I have for my Canon 35mm that I believe can be used on the XTi! Please give me your opinions. Thanks! :thumbsup:
