Hey qwert!
I think you should use a mixture - being fanatical (which i've seen waaaay too many designers be) is just going to make you work extra hard when trying to achieve something..
seriously though - i use a mixture...sometimes for positioning, sometimes for colours and sometimes for effect - but in heart i stay with tables - it's my pet love and i'm faster with tables than i am with CSS (could of course be the lack of practise/need to
keep to one technology only).
Regardless, quiet a few of the web controls that you use renders the html in tables - so ultimately it doesn't really matter.
KISS ~ Keep it so simple ~ whatever makes you rock
