Very interesting - and who do you work for? Looks a bit like advertizing to me.
I've seen many of these come and go while in the SQL team - rarely can they salvage as much as you can get doing it yourself.
For a free solution, checkout emergency mode repair that we included in SS2005 - blog posts about it on my blog and my old MSDN Storage Engine blog. This will always salvage more data than one of these tools can.
