I know I'm a little late, but I've got an article that my husband wrote, if it will help: http://titusbartos.com/inside/recommend/
This article details many of the most popular cameras on the market, from beginner to pro. He gives price ranges, recommendations on lenses and other accessories, and the best places to shop.
We just started a photography studio, Made in Murfreesboro Photography (MadeinMurfreesboro.com), and my husband, Titus, owns a Nikon D70 and D300. He is currently teaching a photography class at RTA (Rutherford Tutorial Academy). If you have any further questions, just ask me or post on his website and he'd be more than happy to help you out.
You can also check out his photoblog at: TheObviousPhoto.com
You can see what kind of shots you can take with the D70 and D300, and with the lenses that he has.
Hope this helps! Merry Christmas!
L. Bartos
