i've used the "cssclip" type style sooo many times. i use java on the top left, below the fancy interactive header. smooth cornered tables. sells like hookers man. Quick tip for all you others:
when making the designs, be sure you use "web colors" there will be a check in your color table in photoshop. This enables the images to load quicker. Quicker image load times have proven to lead to better sales. mention this to the customer and your salary may increase
