More About Trackman FX

I am really obsessed with these trackballs. I think this is the best trackball model has been manufactured so far and still no clues why Logitech stopped making them.
I got two from eBay. I noticed that there were different models and with some subtle difference. P/N 804251-0000 is a little whiter and P/N 804272-1000 is a little yellowish. The cable and PS/2 connector of 804251-0000 are all dark grey. They are light grey and green for 804272-1000 model.

They both cost me more than getting a brand new current model Trackman Marble. However, I am quite happy and will hold on to them until Logitech starts to make them again.

Yabee!
