IBM Human Ability and Accessibility Center: aDesigner. The simulation tools are scary - no more grey on grey menus. It is frigtening what happens to you ability to see contrast as you get older - it is happening to me

and is going to get worse.
This firefox plugin is a must and has built in accessibility checker

I think something like 40% (if I remember the presentation rightly) of Web users have accessibility issues of some kind - many people often assume that accessibility means catering for people with visual impairments of some kind, but it includes people with learning difficulties, dyslexia, deafness and problems with motor skills (navigation keys)
Some tips I picked up that are a real pain for blind Web users - links open in same browser window, use meaningful title tags for links, make anchor text meaningful i.e. not read more etc, give all images alt tags and leave them blank if they add nothing of interest e.g. don't use alt="logo"
