USB Wii sensor bar? Which one?

[JDubbed]

Ok, getting tired of having to configure buttons for different games and trying to configure it just right so I have considered looking into getting a USB sensor bar. As I understand it is a Wii sensor bar only it plugs into your computer and you can use it with Dolphin rather then plugging into the back of the Wii. I would like some feed back on them.

1. Which make/model USB Wii sensor bar do you recommend?

2. Will all of the USB Wii sensor bars work with the Dolphin or are some recommended better working then others?

3. Is there anything I should considered before I purchase a USB Wii sensor bar?

Any other feedback would be greatly appreciate. Thanks
