Looking for a new bag?

I've been looking for a new camera bag that is suited to the kind of photography I'm doing these days. Basically I'd like to find something that can accomodate an SLR, two lenses, a flash, and a laptop with cables. To me, this seems like a pretty standard setup for someone who is taking digital pictures, but I haven't had much luck in finding the right bag yet. Today, I ran accross M Billingham and Co in the UK. They seem to have a wide range of very sturdy photo bags. The nice thing about these bags is that all of the internal seperators can be removed, and then you have a nice general purpose business case as well. I found out about this bag from a blog about the Palm Tungsten T (Thanks Tom). Of course this comes with a catch. The company appears to operate mostly in the UK, and I don't know if they ship to the states. If anyone has some expierence with these bags, or this company, I would love to hear from you. Just email me at allen@hutchison.org.
