It's over at http://forums.cnet.com/7723-7588_102-354911.html

It lists many of the free and free to try titles. I give the nod to Zero Assumption Recovery but my advice about data recovery is simple. If your files are irreplaceable then you may want to try the titles but consider http://www.drivesavers.com if you can't risk it.

Now that you see the price of recovery can I ask this -> How about a backup copy? Why not a few files you can't lose at your DROPBOX? (see google)
