What Does Your Warehousing Picking System Look Like?

Sanitary Maintenance's May issue ran an article on new warehouse picking technologies. We covered everything from scanner guns to pick-to-voice and pick-to-light systems. We don't expect that many of our readers use pick-to-voice or pick-to-light systems, but we felt it important that you all know that the technology exists and that scanner guns are quickly becoming a dated technology. 

So we're curious: What sort of picking system do you distributors currently use in your warehouse?
