Grease recommendations for worm gear?

I should also mention it is more aesthetically pleasing to have a whisper quiet card reader than a noisy one. To me, it somehow exudes a sense of quality. Which I think is appropriate for these HPs. On the ones I have now, the motor/gear noise is on par with the faintly audible 'ting' you hear (from the gold contacts releasing the card) when you pull the card out the exit slot. That's quiet.
