Hiya mate, the KO servos have a good spares backup so you can get a new case if you broke a tab.
The wire is called a fet choke lead or something. it powers the fets inside the servo.. indeed, the fets used to be outside the servo in a seperate box on the early fet servos.
I prefer the simplicity of the 6volt servos since these don't need an extra wire - which is just something else to get damaged and fail.
It really depends how much you want to spend though, the KO servos are among the most expensive around, but they are nice.
