Which are better -- new cordless power saws or the old standby corded plug-ins? The latter has sustained 120-volt power and is relatively lightweight for the punch it packs. On the downside is the need for a power cord that limits its range. The eight cordless power saws we reviewed included two that were quite heavy (more than 10 pounds), due to larger battery power that make them harder to handle than corded saws. Others were lighter, less powerful and more manageable with one hand. While each was innovative in some way, not one cordless saw had all the versatility, maneuverability and staying power of their corded plug-in brethren. But as cordless models get lighter with more lasting power and more bells and whistles, we're betting they'll be on par with plug-ins. And that's the On The House tip for today.
