A Great Mouse has died

It is a sad day. My mouse since around 2001 has died after many years of hard service. I first came upon this Optical Mouseman M-BD53 Rev. B as a warranty replacement on an original Ergonomic Mouseman, which I bought after moving out and away from my original Mouseman. Unfortunately, I haven't found one that quite fills its place in terms of ergonomics and movement. A couple years ago I even purchased another Logitech mouse just to steal its cord, as the original on this one had grown stiff as the rubber broke down. For those curious, this was P/N 201404-000.

Will I find a suitable replacement? Something that I don't have to charge batteries but still feels good and moves right? The search is on.

Do I keep it and troubleshoot the problem? Reflow all the solder? Replace the cord again and hope it is a break in it? With ever increasing frequency in its final weeks it would stop working, power from the USB port would cease and the light would go out. I initially thought my motherboard was on its way out, but another mouse has worked fine with no interuptions. I'll hold onto it for a little while and see if I get ambitious with the soldering iron. Perhaps it will return as frankenmouse!
