We'll usually recommend a power tool when it can do the job it's made for really well. So we'll doubly recommend the Rockwell Trans4mer ($250) for its performance and design. This rechargeable power saw can convert from jigsaw to reciprocating saw in seconds, allowing you to tackle twice more jobs with one tool. It's compact, lightweight and features six cutting angles, an LED light to illuminate work areas and a dust blower to keep lines clear.
