Bosch drills are like comparing a Cadillac to a GEO. I have the 18v drill, jigsaw, and recip. saw, best purchases ever! I also have a Bosch corded hammer drill which is the way to go, using the cordless hammer just beats the thing to death.
I used DeWalt for years, drill was ok, miter saw lasted about 14 months before it was total junk. Now i use Makita 10 dual bevel slide, and also have a 12" Bosch compound. Also have a Bosch Table saw. I LOVE BOSCH, in case you did'nt notice.
The Bosch also has a steel rod that runs the whole top length of the drill on the inside for strength, it can withstand a one story drop right on it's noggin and just chuckle about it. They are so smooth when they run, I pick up my old DeWalt now and it feels like its full of pebbles in comparison.
But back to the issue, (sorry man, I love tools heheh) If you just want something for around the house, all of these drills are over-kill for you, they are meant for daily use by tradesmen, if you don't use it like that, you are wasting money.
One of our guys came to work with a new Ryobi 18v one day and we all made fun of him as we love to do, but man, that thing has lasted a year and a half now and still going strong, and its used hard every day. You may want to consider that, youll save yourself alot of cash.
The other thing to consider is that batteries are expensive and only last 3 to 5 years whether you use them or not. Ryobi batteries will be half the cost. As posted above, the DeWalt and Bosch units go for 80-90bucks a pop.
My boss has a lot of Black and Decker, oops, I mean, DeWalt tools and we are replacing them alot more than we should, but he's not that bright sometimes and keeps buying and replacing them.
Sorry for the long post, but I hope it helps a little, don't be scared of that Ryobi for home use, it has proved good for my buddy, he now has about 8 Ryobi tools. (he's a cheap-skate)
