Dell Small Business offers its Dell M109S Ultra Portable LED DLP Projector for $499. Apply coupon code "9Q26N641C6QSDC" and it falls to $399.20. With free shipping, that's $100 off and tied with last month's mention as one of the least expensive DLP projectors we've seen. Sales tax is added where applicable. This 1-lb. portable projector features an 858x600 native resolution, 800:1 contrast ratio, VGA and RCA inputs, and more. Since it uses LEDs, it's unlikely to ever need a bulb replacement. Deal ends November 26.
