I had (or still have actually) a 10D, but back in them days EF-S lenses weren't around, so I would have been made to look stupid by saying it will take these as it's a crop frame. After dumping my original Sigma 28-300, which was trully awful only I didn't realise it at the time, I got a Tamron 28-75 which was excellent. But it might not give you as wide a view as you would want. For wide, I got a Sigma 15-30, which I still use on full frame, and it's good for me.
The 10D was, and still is a good camera. Don't let anyone give you any cause for concern about it being only 6mp. I've printed A3 from this. I once met the lady who runs the Dreamstime stock library site and she told me that their best photos (3 years ago) were coming from the 1D/1Ds series and the 10D.
