Napalm is 100% correct.
B/D, to sum it up, is not as high of quality as a Milwaukee or a DeWalt.  They can last a long time if taken care of (My little B/D drill is still kicking.  Made circa 1960's) but are not as durable as a higher brand.  You get what you pay for.  I use alot of tools on a daily basis where I work, and I have to say from experience, that if you kick the extra for a good Milwaukee will save him heartache later.  Milwaukee is my personal fav, because their tools have more torque and grunt then the B/D, although any of the top brands are great.
Want proof?  Look in any good contractor's tools.  When you see someone getting work done on a house or something, look at the tools they have.  Very seldom do you see a professional contractor using B/D tools.  Milwaukee, DeWalt, Porter Cable, etc. all have expensive tools for a reason.  This is why.  
B/D is not bad at all, but for daily use, I'd steer away from them.  B/D is good for occasional home use.
