I decided.
I went with the Canon 40D with 28-135mm lens. I added a Speedlite, spare battery, UV filter, flash card, and a few other things. It was a lot more than I thought it was going to be when I first started looking a couple months ago, but I'm sure I have a good camera system. The other cameras that I mentioned at the start of this thread all looked like they would have worked fine, but this model seemed to have all the good points from the others and a few more, too.
I bought it from OneCall.com and believe that I got a good deal. I've bought from them before about nine years ago when we bought our camcorder. They treated me nice back then and yesterday, too. FedEx will deliver it Thursday! Thanks for your inputs along the way!
