Need to cut some studs or joists in an attic or crawl space, or prune trees, cut branches or trim fence posts around your yard without dragging an extension cord around behind you? An 18- or 20-volt cordless reciprocating saw offers decent power, a useful amount of runtime and as much cutting versatility as a corded model. Although most cordless saws are pricier than similarly featured corded models, there are economical choices, including the Porter-Cable PC18RS and Ryobi P510 “One+” saws. If you already own cordless tools, you can save money by purchasing a recip saw that uses the same battery pack and charger. For example, the full-featured Craftsman 26314 20v Li-ion Professional recip sells (sans battery) for $79 in 2009, the same price as the Skil 9225.
