I'm planning on finally retiring my Logitech T-BB18 trackball. I'm getting a white M585, and putting a T-BB18 ball in it to make it look more like the T-BB13 I had in my teens. I've already tested this, it works. What would really set it off (other than seeing if I can dye the scroll wheel red) would be to get a nice little vinyl sticker of the old Logitech logo. But I can't seem to find anything.
I thought about just getting another T-BB13, since it was actually USB. But, I remember what a pain it was to take out the ball and clean it. I'd rather get a new M575 that is both Bluetooth and dongled USB.

I think I might just skip the whole logo thing. The red ball is enough to make me happy. It's gorgeous.
