Thanks for this URL.
This is a good opportunity to point out that the WAI ERT and EO 
working groups also have a database of accessibility evaluation tools at
I believe it contains over 50 tools and there is an RSS feed with 
notifications of updates.

Some tools in the list at VirtualHosting are not in the WAI list (but 
some are not accessibility tools in a strict sense):
* UITest.com
* Webnauts
* Graybit
* 1-Hit Load Time Analyzer
* JuicyStudio's CSS Analyser

The new WAVE 4 is not in any of the above lists 
(<http://wave.webaim.org/>, <http://www.webaim.org/blog/introducing-wave-4/>).

True. I don't know of any tools that can fully check more than 30% 
(or was it 25%?) of the WCAG 1.0 checkpoints.
