[G4] USB Keyboard extension cable?

[diane]

This has finally bugged me enough to do something about it and I 
didn't realize they had that stupid nub in them till today.

I use the Apple USB extension cable for my keyboard as I have the kb 
in a kb drawer. But it's still not really long enough as my CPU is 
behind my monitors.

Is there a proper extension cable that will allow me some more 
length? Or do I need to change to a non-Apple keyboard?

Thanks,

Diane
