I agree BOB. IF you're using a tool every day for 10 hrs. a day, you need to spend the extra money on THE BEST YOU CAN AFFORD. And usually, corded is the way to go in this case. The only tool I personally would use for that length of time/duration is a drywall screwgun on a large commercial job. Have an old B&D "scrugun" that's probably 20 years old that's only had brushes and trigger replaced (and I bought in a pawn shop used). It has hung thousands of feet of board and framed many walls. I don't think the OP is looking at full time use. Hey, I'll send you a check for shipping to Atlanta on that Ridgid set if you want to be rid of it that badly......

I am not certain, but I think you can get the Ridgid compact drill and impact driver as a set for $129 right now at HD.
Thanks for everyone's advice. I didn't find the Ridgid set for $129 at either of my local HDs, but I picked up a refurbed Makita 10.8 set for $119. It's got the drill with the 1/4" drive, but that should work for now.
