I own and love a Microsoft Trackball Optical 1.0. The trackball is thumb operated and it has 5 configurable buttons (including depressing the scroll wheel). Of course I seem to be the only one left in the known universe who likes a thumb trackball since Microsoft and all other mouse manufacturers seem to have stopped making them.
I am worried that if anything happens to this one I'll be forced back into the pack having to move the mouse around or using an ordinary trackball. I have thus searched a ton of stores on and off line and have gone to eBay in desparation. On eBay the few I found were from questionable sellers, used (too risky), or more than I want to pay (especially since I don't believe any are really new - I have puchased new on eBay before and gotten reconditioned).
Picture is attached and info on the product can be found here: http://www.microsoft...9724d3d&type=ovr
Bottom line: Anyone know of a reliable source for the product or a comparable product that I have somehow failed to come across in my search? Maybe you have one you didn't like and so didn't use much tucked away in a drawer?
BTW - this is the one and only Microsoft product I have ever owned that I really liked (although I just don't have enough motivation yet to change OS). I have had it since 1998 if I remember correctly and it still works perfectly - with occasional removal of lint.
