Thanks VTi and Stetson. Yes, I'm only considering Canon products. I'll go ahead and buy new as I can afford the pieces, and watch for rebates and sales. I remember you mentioning a new Canon being released soon, so hopefully that drops the price of the 5D a little. I'm not in a huge hurry, so I think time is on my side in this game.
My photography interests are all over the map. I love photographing scenery throughout the seasons, but also enjoy trying to capture decent wildlife images. Both have their challenges, but I really can't see any down-sides to the digital approach that allows me to bracket, then cull and sort once I get home. While I'm amazed at the portability of my little shirt pocket Canon, I'd like to make room in my pack for a bigger camera that does justice to some of the subject matter I find. I'm not much into photographing people, and can continue to use my Powershot for holidays and informal events. Once I have children my feelings may change on the subject however.
VTi, the images you've shared here are an inspiration, and are a benchmark for me to aim for. I realize that you're using the very best equipment, a solid tripod, and a vast foundation of knowledge and experience, but why should that deter a little guy like me, right?
