WinUndelete

Anyone know if WinUndelete is a good program? I was looking into Executive Software’s Undelete, but it doesn’t seem to be compatible with Windows ME, and that is the operating system I need to use it with, unfortunately. WinUndelete says it works with ME, but I’ve never heard of the company or the product, so I don’t know what to expect. Also, I have to install it on about 7 computers. I’m guessing I’ll have to buy 7 copies? Any opinions? Here is the link to the site for WinUndelete: http://www.winundelete.com/
