Presently have an Hitachi cordless 14.4v. impact driver. Use it for driving
screws into wood. Very pleased with it so far. But this is my first ever
impact driver, so I don't really know whether I should be impressed with
Hitachi or the fact that I'm now using an impact driver for screws rather
(ostensibly a better match) than my (corded) drill driver. That said, I am
in the market to buy a cordless drill driver (since I discovered my impact
driver is not quite as handy as a dedicated drill for when used for
drilling). But I'm kind of torn between my long time admiration of Bosch
tools and my current infatuation with Hitachi (or, at least, their cordless
drivers). And since I'm not independently wealthy, I can't afford to just
by one of each (although that would certainly make for a more fun
afternoon). Therefore I'm seeking opinions/feedback/advice/experiences
related to cordless drill drivers by Bosch and/or Hitachi (and/or any other
decent quality brand worth mentioning). Thanks in advance.

PS: Bosch and Hitachi both make a 1/2 in. drive 18v. drill driver that puts
out up to 550 in.lb. of torque, even though the Hitachi one uses a 3.0
Amp/hour battery whereas the Bosch uses an only 2.4 Amp/hour battery.
