Ending today, Groupon offers the factory-refurbished Neat Company NeatDesk ADF Scanner and Digital Filing System for PC or Mac for $199.99. Coupon code "HOME10" cuts it to $179.99. With free shipping, that's $90 under our mention of a refurb from a year ago and the lowest total price we've ever seen. (It's also $180 under the best price we could find for a new one.) It features up to 24 PPM dual-sided scanning, image capture support, and automatic document feeder for multiple size document scanning. A 90-day Neat Company warranty applies.
