New site looks good. Maybe include a google map on the contact page. Grid vs List view does not work. Images on product pages don't always display properly (e.g., they zoom in too far that you can't see the product -- ATI fixtures). Meta tags needs to be setup properly for products (e.g., search for Bubble King and I get zeovit listings).

The site is still operating and fully browsable. Did you know this Dave? You need to disable the site through the CMS and not via DNS redirection.
