+1 on Crumpler. I have the 5 and 6 million dollar homes and I love them. A small SLR fits nicely in the 5 million dollar home with a lot of room to spare, but if you need to carry more the 6 million dollar home does the trick.

They also have fantastic backpacks if you find the weight is too much on one shoulder. Their "barge" bags are really nice for a smaller SLR.

Oh, another great thing about Crumpler bags is that they look really nice, and don't look like camera bags at all, so no one will know there's expensive equipment inside.
