I'm just finishing up building a cabin on my property and the most valuable tool I've purchased has been a Ryobi impact driver.
I'd used a friend's Milwaukee and liked it but had to keep costs down, so Ryobi it was. $149 in NZ for the skin, battery and charger, plus $40 for some decent impact rated bits. Honestly it's done everything from putting the frames together with bugle head screws to putting on the roofing iron, the cladding, the lining. I love that thing.
Now of course I already have the Ryobi hand vacuum and I even went and got a Ryobi 2 stroke trimmer. That weekend warrior call is right for sure - decent enough quality and good price.
