Home Depot offers the Bosch 50-Foot Compact Laser Distance Measurer, model no. GLM 15, for $29.88 with free shipping. (Lowe's charges about the same with in-store pickup; Amazon charges about the same with free shipping for Prime members.) That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's the best deal now by $17.) It measures in metric and SAE increments and features an accuracy to 1/8" at 50 feet.
