And here is a photo with the Pentax (no tripod, even):
Here are the contenders (as of today, right now) and I'll give you just the minimum of data:
Nikon D7000 (about $1200 stark naked, meaning no lenses.) 16.2 megapixels, ISO 100-6400.
Canon EOS 60D (about $1400 with one or two lenses depending on where you shop and what you know about lenses. I have a lot to learn there!) 18 megapixels, ISO 100-6400.
Nikon D90 (about $950 with one lens.) 12.3 megapixels, ISO 200-3200.
Canon EOS 50D (about $800 naked.) 15.1 megapixels, ISO 100-3200.
You can see this is a major investment just for the camera body. So I'm talking to everybody, testing other peoples' cameras at parties (yes, just last night!), looking up photographers I admire to see what they actually use, and reading page after page of chat boards and reviews online. I finally had to give myself a deadline or this could go on forever. By the end of next week I must order a camera! Really, I could probably get just about anything made in the last two years and see massive improvement. But I don't want improvement, I want perfection! Meanwhile, I'm still gathering data, so, hey, what do you use, and how do you like it?
