My MacMe skin has very few tables - http://www.xd.com.au/free+skins.xd , and this forum post on the aspnet forums might help you in your quest for tableless skinning -

Armand Datema - Nokiko on the forums does alot of work with css as well.
In my opinion, and I'm not sure if Salar has the same, but I suspect it would be also along the same lines - If you are a newcomer to DNN, and you want to do tableless skinning, you will have challenges - DNN isn't ready for it yet and you might like to spend your time working on things that give you smiles, not headaches.
There are a few sites that are going down this path, but I have found that it's not produced the highend commercial results that a few tables can do. There are other ways you can optimise a skin without having to go downl the CSS only path.
That's just my thoughts on the matter, but I'm always open to hearing someone coming in and breaking new ground, as long as it looks good .. no point in saying you can make it work if it only looks good with 2 panes, 1 image, no content and in IE6 only.. .and.. only using 3 modules becuase the rest may make the skin fail... .. And it also has to look good in Admin mode for it to be really a sharp solution.
These are just some of the things that may need to be overcome.
