Popular Mechanics has posted a round-up of 18V Impact Drivers.  These extremely versatile tools can be used for anything from installing a garage door opener to building a deck.  Although many folks don’t see the point and will continue to use a regular cordless drill, once you use one of these guys you’ll never go back.  The prices in the Popular Mechanics round-up ranged from the $395 Bosch 26618-01, to the $170 Ridgid Fuego R86030.  The Makita BTD144 proved to be the winner, earning 4.5 stars, but at $350 its not cheap.  The best buy is the Ridgid  earning 4 stars and only costing $170.  The Porter Cable PC18ID also deserves a mention, only costing $20 more than the Ridgid, but having a battery that lasts almost twice as long.  Sadly the article lacks significant detail beyond the specific likes and dislikes, but its worth checking out if you’re in the market.
