if the sound of mouse clicking is such a big deal for you that it prompted you to make a post, you must live a very pampered and luxurious lifestyle. That's what I thought, but then I saw you added that it must be reasonably priced. I think you should borrow a dog, a cat, and a donkey, let them roam your house and do as they please, and in one week, get rid of them, and your mouse clicking problems will be gone. I read a story and this definitely seemed to work, ymmv though, and I'm not paying any cleaner bills.
