According to consumer reviews, the Bosch 4100DG-09 (est. $725) receives high points for its accuracy, convenience, and additional features. For those on a budget, the Craftsman Professional 21828 (est. $330) also receives high marks. The Craftsman includes good safety features, but many have noted that it makes a lot more noise than the Bosch device.
