Your post embodies what many of us here try to pass on, that it's more the photographer and not the equipment. We tell people that you can't buy great photos by buying a DSLR, just like you can't make great meals just by buying pro cooking equipment.
I'm not a fan of flash based sites, but your photos loaded up pretty quick in the slide show.
I have shot all of the photos seen in my photography blog - stylepeterson.com with the cheapest DSLR cameras and kit lenses on the market including the Nikon D40, D60, Olympus E-410, and Rebel XT. The camera you buy will not have as much impact on the quality of your photos as the effort you put into developing your skills. Buy waht you can afford, and shoot, shoot, shoot! Your comments and critiques of my photos will be appreciated.
