Tables vs Tableless layouts?

I'll offer one of my recent sites as a good example - www.contemplate.us - there are a few broken pages if you go beyond page 2,460.

As another example I'll offer my portfolio site - www.yournewdesigner.com - this was my first attempt at CSS layout so the coding leaves a little to be desired... It all validates but I've still got javascript rollovers and the coding is not great with all the nested divs going on.

In 2 weeks I'll have completed my 4th CSS project - this time for a client - hopefully this will serve as an excellent example of tableless, accessible design.
