Please review our new company website -
It's generally table-less CSS, the only ones in there are generated by the CMS. A pain that we haven't had time to hack out, yet. Will probably wait for the next version of Joomla, which apparently won't have any.
The content is well old and is next on the list for a rewrite.
Site looks good, the homepage validates, however, you have bunch of warnings. ( such as a href tags having no value)
Subpages have some errors, simple things you could fix pretty easily.
Did you use joomla for the cms?
