Cordless drill/driver/impact for dummies!

I use Milwaukee M18 series. I have over a dozen different M18 tools and love them all.
The 1/2" impact is nice and I also have the 3/8 version. I just picked up the leaf blower this week.
Lowes sells cheap sets but cant comment on quality. The biggest difference is in the batteries.
Once you get a few batteries you can buy the bare tools and they are fairly cheap. The batteries are most of the cost.
