Impact Drills are about 10x the cost of a cheapo drill at the shop. But WOW are they worth it. The Makita in particular is a great device. The 14.4v lasts a long time (much better than the regular drill). You don't realize until you get the torque at high and low speed how much you needed it. - no more stripped screws. I have driven 1/2inch bolts into the wall with this bad-boy and I know I didn't want to have to do that with a wrench. There is NO WAY that a regular drill could have done it. It's also great for quickly spinning wheel nuts off of the car to change a tire or do a brake pad change etc.Get the 14.4 instead of the 18v. It is lighter and more controllable. That helps a lot when you're trying to balance the wood, hold the bolt etc. I have the NiMH, I don't know if the new LiON "LXT" is worth it. The older NiMH works very well for me so I don't see the value in the extra money for Lithium.Get this kit instead of an impact on its own to get a second battery. I use the regular drill in parallel to drill the pilot holes etc so it's quite useful. The standalone light is good too, but I don't use it - I don't work in the dark :) The light on the impact is really nice to have.Having 2 batteries will allow you to use both at the same time as well as allowing you to go all day - the second will charge while you work with the other.
