Get one of their Deluxe models that has everything from the brass scrapers, brushes to the different patches. I've added their kits to my other kits. They work well. Of course, like others have said here, don't forget to get some items not included in their kits to aid you in doing some of the other cleaning chores for when you do more than a "field cleaning".
