Hi Brad,
I still use tables most of the time to control layout & positioning (personal preference), but I use stylesheets heavily for design elements to keep graphics minimal.
Here's a few mainstream samples:

You can find more at my homepage:

My style is slightly different to those examples you posted & my clients do like lots of photos in the designs usually, but I think my work is fairly clean & I work a lot in mainstream design.
If these suit what you are looking for you can contact me on either carlajayne at gmail dot com or 3422430 icq
Good luck!
