I'm definetly leaning towards the XTi, just wanted to know if there were other models to consider if they popped up for sale used.
I'm also planning on picking up a compact pocket camera that I will actually carry with me everyday/everywhere on my trips.
Otherwise my big camera tends to get taken with me on large trips. Mostly nature photos/landscapes. I'm interested in learning macro as well, and I'd also like to be able to do some low light family photo's, so I'll probably hang on to a kit lens and pick up a zoom that goes up to 300mm.
The Xti kit has fallen below $500 a few times, but isn't regularly available for that.
