How to purchase/connect a sensorbar

[che]

Hey I hope this is the right forum for my problem.^^
I just saw, that many of the members use a sensorbar, connected with the pc. Do you guys use the Nintendo sensorbar or a 3rd party one? And if it's the original, where did you get it?

Thanks a lot.

Lg,
Julian
