That one's good.  You might also look at RxToolkit (can't turn up the URL
right now, but it's not the one in Komodo) or RegexBuddy
(http://www.regular-expressions.info/regexbuddy.html).  I personally like
RegexBuddy better because of the way it displays the match, but then, it's
shareware at $30, which bugs some folk.  There's an interesting example of
it on the blog http://www.codinghorror.com/blog/archives/000027.html.
http://en.wikipedia.org/wiki/Regular_expression is interesting, as well.
