Looking For A Bare Bones Pinging Tool

I'm looking for recommendations on a basic pinging tool...something that I can load a ping list into and then load a list of URL's and it just goes down the list pinging the URL's. I don't need any more than that but if there's a "bundled" product out there that has this piece as part of their package, let me know.

I use the blog pinger that's part of the bloggergenerator package but it's been giving me some problems so I'm looking for alternatives. Thanks for the help.
