I just bought DeWalt's DW0521 1/4" hex shank keyless drill chuck so that I can use regular drill bits with it as well. A bit heavy on the front end with it attached but still a piece of cake to hold and use.
That little impact driver is excellent for driving long screws into a 2x4's thinner edge which basically means you're screwing them all the way into solid wood. When I attach shower assist bars onto studs, that little impact driver makes inserting and running tight 6 long stainless screws absolute child's play.
This tool is great. I've had it over 1 year now. I also bought a hex chuck for it, but got it from harbor freight for only $5.99.
This tool is great when using in tight spots, like putting up blinds. The only issue is the hex chuck, as hex bits break easily, and hex chucks don't tighten as well.
