If you're serious about this then don't blow your money on those above cameras. You'll like them at first but you'll grow out of them and be annoyed by their limitations, IE shutter lag, being stuck with one lens, no raw mode, etc quickly. I've learned the hard way. You really need to get a Digital SLR. You can pick up the Canon Digital Rebel at Amazon for $899 with the basic lens. Here's a site with links to tons of reviews and other stuff on this camera. Also there is hacked firmware which will basically add the features of the 10D which is $500 more.. This camera is awesome. Over 100+ lens you can use with it.
