BenQ continues to take 15% off its refurbished projectors via coupon code "MAY15". Plus, all orders bag free shipping. That yields prices far under what you'd pay for these projectors new. Deal ends June 1. A couple of best bets, with prices after coupon:

• Refurb BenQ MW526A WXGA Portable 3D DLP Projector for $277.95 (pictured, $116 less than new)
• refurb BenQ MX810ST XGA Short Throw 3D DLP Projector for $413.95 ($73 off)
