What about something like this?
I should point out that ebag's build there is pretty complex compared to a standard flat pack. I'm sure someone could build it for you but it will definitely be more expensive than the flat pack offered here (and which sounds great, BTW).
So, if on a budget, go for the simple flat pack Danny put in the first post.
If you have more $$, then a more complex build like ebags is possible. And it's freaking beautiful!
