Ok so after a lot of research I have decided on buying the Canon Rebel XSi as my first DSLR. I was looking online for it and stumbled across this site: Canon EOS Rebel XSi 450D 12.2MP Digital Camera W/ 18-55mm IS Lens Obviously the price they put is very cheap. $312. Is this site real or a scam? If you can tell me, that'd be great. Thanks.
