Saddle bag advice

[PhotoByBike]

I'm seeking a good (large) saddlebag that's big enough for my Canon G9 and accessories, phone, wallet, tools, change of clothes (shorts / t-shirt), energy food / drink mix, and a couple of extras. I'd like to be able to take it off the bike and carry it around with me when I go into a store / go to eat, etc, so something with a handle or even better, a shoulder strap would be great.

Something like the Carradice Pendle or Nelson I think would be perfect, but I don't think they have a shoulder strap or handle.

Does anyone know of something similar in size (or a little bigger) that fits this description? It's going on the back of a folding bike so I actually have a lot of room back there to work with.

Thanks in advance.

BTW, the saddle is a Brooks B17, and I have about 1.5 - 2 feet of clearance above the rear wheel.

I have a handlebar bag on my folder, something like this:

What I would really love is a large saddlebag that could also be used as a decently sized messenger bag. That would be just awesome. I would buy something like that almost no matter the cost. (I can't believe my penny pinching self just said that)

Where are the flying cars and the saddle/messenger bags I was promised? ;)

A Zwei bag with a Klickfix seatpost mount is pretty close to a "large saddlebag that could also be used as a decently sized messenger bag". I saw the Zwei bags in Barcelona this past winter, and I was very tempted, despite having too many bags already! Wallingford says it's going to be selling Zwei -- maybe I'll break down when they're for sale in the US.

Nice. Though I wish there were better pictures showing how much it can carry. Also, it comes with the handle bar adapter... wonder if it will work with saddle bag adapter too. Either way, it's pretty nifty.
