Sorry Zach- I shoot Nikon professionally- and would not suggest that over the others mentioned. The Canon 50D is a different creature altogether, with a magnesium alloy body and a 15mp sensor. The 40D is certainly worth a look too, as it's price dropped with the addition of the 50D. Same metal body, but the ISO isn't as high and the sensor is 10mp. The Olympus is a niche camera, with limited lens and accessory options. Nothing near Canon or Nikon. Pros stick with the big two for a reason. The D5000 finally addressed my issue with the D40, D40X, and D60. A three point autofocus system. Any photographer knows the rule of thirds, and this focusing system totally ignores the four major compositional focusing points. Complete fail. The D5000 steps up and has 11 point autofocus. Much better, plus you might be able to use the HD video on it. For me, the video and tilt screen don't mean much, but you be the judge there. www.dpreview.com is the best unbiased source of information there is.
