We started with the cutter you linked to and I HATED it. We now use the Olfa Ergonomic. I find it much easier to use and you don't have to remember to close the blade. I have seen video of the Martelli cutter and it looks interesting, but I'd hate to spend that kind of cash and find out I don't like it. I keep hoping to see someone using it at a quilt shop so I can ask for a "test drive."
