Wow there are some lovely photos there!
I also went down the Canon and need to make more use of my Cameras. I started with a 300D which lasted me a good few years. Motorsport has always been my thing and I was always nervous with the 300D as it didn't have any weather proofing. I then got a 30D which I've had since 2006. It's still fully functional and I tend to use it as my second body. I grabbed second hand 5D to try full frame and fell in love - the wife has this as her full frame body now as she shoots the occasional wedding fro friends.
My main camera is the 6D which I bought as they released the 6D MkII and got a great deal on.
Unfortunately I'm lacking any decent lenses at the moment as I had to sell a bunch of gear some time back to raise some money. They'll get replaced one day but only once I start getting the most out of what I have.
