Sailor:
I have not been able to look at Crumpler bags in person, but notice a lot of the forum members have 'em and like 'em. Here's what I found that pleases me, the Lowepro Omni Sport. Very compact, will easily contain your set-up plus some extras like a small flash and even the battery charger. Has a great shoulder strap and concealed waist strap, too.
Measures 11 1/2" X 5" X 8 1/2". The Omni Sport will also fit inside a Pelican 1400 hard case for extreme circumstances, too.

If you search with Google, you can find an international dealer with a bunch of pictures of the bag, too.
