That is actually the best solution i have seen, usually when it comes to making column layouts using DIV’s you need to use hacks because they don’t work in IE 6, 7 & 8 but that looks pretty solid.
I’ve tried that layout (and others similar to it). Not bad, but I actually find it easier to write the CSS from scratch than to adapt someone else’s. Ends up being less work in the end, and then you know the guts of your own site intimately. You might check out css Zen Garden for some good inspiration and information.
