Nice shot CruzDude! What kind of DSLR did you use? I'm planning to get one soon, but I'm stuck between the Nikon D80 and D200, the Canon Rebel XTi and the Sony a300 and a350.
According to the exif data he has a Pentax K10D, this is also the camera I shoot with and its a nice system. Canon is also good but I liked getting image stabilization in the body since I could buy slightly nicer non-stabilized lenses that way. I'd stay away from the Sony.
Of the cameras you mentioned I think the D200 is the best, but that's because I don't like the smaller body sizes of the Canon Rebels, maybe you would. Canon also upgraded the XTi to the XSi which may or may not be better but if you can find a bargain on the 30D I'd consider that instead. Before I had the Pentax I shot with a Canon that was unfortunately stolen and I had to start over.
Try the Pentaxes if you can get your hands on one too. If you are going to use the kit lens or a lot of 3rd party lenses it is a ton of bang for the buck.
Just keep in mind that you're probably spending the most up front on the body but what you're really buying into is a lens system, take a look at which company offers the lenses you're most likely to use at the best prices and go with that.
