So, I LOVE my Mighty Mouse, but, it has finally somewhat kicked the bucket. I've had it since November '07 and it has sustained heavy use. Now, the mouse wheel will not scroll down. At first, I thought this was simply the dirt issue again, but no matter what I do it will not change. So, there are two ways I could solve this problem: 1. Try to open the ol' mighty mouse and fix it (which, I would love to do) 2. Buy a new one (not something I want to do) If no one will give me a how-to/point me to one, could you suggest a place to buy a mighty mouse for cheap (wireless) or a 4-button mouse that might perform well that I can get for cheap?
