Looking for a new camera body.

[AgilityPup]

First off, I use Canon gear right now.

I have a Rebel XSi right now and I bought it used, and it works great, but I'm thinking that before long I'm going to need a new body. As of right now, my meter is about a stop off so I always have to meter for a stop down, and it's just a pain in the butt. So I'm looking for a new body... I only have the kit lens and a 55-250 for this camera (well, and my 70-300, which I hate) so not a lot of lenses, but I'd like to stick with a body that I can still use those lenses for.

I'll likely be doing dog sports/sports photography, maybe some outdoor portraits, but I'll likely never do anymore studio work after I'm out of school, so that's not a huge focus for me.

So what do you have? How do you like it? What do you recommend?
