Looks Like a Useful Service. From Internetnews.com, "Sue a Spoofer Today." I question whether it's really necessary to have a separate trademark registration specifically for your domain name. As long as your company's trademark is incorporated into the domain name, I think you could prove confusing similarity. The cost doesn't seem to be that far out of line (although I question what could possibly be in the "Build My Case" kit for $125). But the website really could stand to be toned down a bit - they're trying a bit too hard, which makes it sound like they're trying to sell you snake oil.
