I thought I'd mention two more things about this drill now that I've played with it a bit more. First, I was worried about the chuck like a lot of you. It's a heavy solid chuck. Yeah the outside of it is plastic but the innards are metal as is the mount to the output shaft of the motor.
Also, the chuck is HEAVY. It feels very solid and I don't think anyone should be worried about it.
Here's a little picture show to maybe help people decide:
First, just some shots of the chuck externally.
This is how the interchangeable chucks mount to the output shaft of the motor. As you can see there's a recess in the outside of the shaft that a ball bearing detent locks into. When you pull the orange part of the collar forward you allow the ball to slide into the chuck and release from that recess.
I tried to get a shot of the inside of the chuck and it's a little hard to see but I think there's enough there to understand it. The inside of the chuck is a really solid and thick metal sleeve, containing the ball detent. In addition, you can see that the actual connection from the chuck to the output shaft of the motor is a hexagon shaped metal shaft which is very tight and transfers the power.
I would say if anyone is in need of a really powerful and super nice drill just get this one and don't worry about the chuck. I was and I think it was unfounded. For 169$ I don't think you can beat this thing for a full size non compact drill. Every part of this thing just feels awesome. I can't stop playing around with it. I keep moving the case around and thinking that I can't believe how nice the case even is.
Also, a warning... I would NOT advise trying to chuck down the drill by driving the drill into your hand. That's how I always opened and closed the chuck on my old cordless drills. Well this thing has some serious power and when it really gets going because it is so fast... I burnt the DANG out of the inside of my hand trying to stop the chuck. I've got a nice line burned where the edge of the chuck was. This isn't a big deal in practice though because it has a ratcheting chuck that actually seems to work well unlike some of my other drills. I used to drive the drill to tighten the chuck because if I tried to use the normal ratcheting action of the chucks the bits would just fall out. Not the case with this drill.
