this is from 2008!
Well, the "Do 404s hurt my site?" part is dated May 2011, but that doesn't necessarily mean the advice there still applies.
I note in passing that there is a link ("help them find what they were looking for") that supports the use of custom error pages:
Another possible problem with doing that if you have a large number is that (in my case, anyway) WMT reports duplicate title/description tags for 404 pages: it treats the content of the custom error page as if it was the content of the missing page.
