Lowe's offers the Bosch 50-Foot Compact Laser Distance Measurer, model no. GLM 15, for $29.97. Opt for in-store pickup to dodge the $5.99 shipping charge. That's $10 under our mention from a year ago and the lowest price we've seen. (It's also the best deal now by $20.) It measures in metric and SAE increments and features an accuracy to 1/8" at 50 feet.
Of note, Home Depot offers it for about the same price.
