Dear Hacklordsniper:
--I agree with robrenz that a clutch would be a good thing to have. But it seems to me that most lever operated screwdrivers have variable speed and need not be going full tilt at all times. After all, even with a clutch, there is rotational momentum to consider. That is why people often ease up on the RPMs when the screw is almost home. I also think that most of the good ones have clutches. I think eBay is a good source for, if nothing else, information. The question about obtaining extra bits is still pending. Let us know what you find out.
