I have the ratchet and 3/8" gun that O'Reilly sells... I've used the hell out of the gun, but not a lot of the ratchet. But it's there, and given what I paid for it, I won't cry if it walks...
I am just a few blocks from both a Home Depot and a Harbor Freight... I looked at both the Bauer and the Ryobi tools, and... I have a half-inch drill, 1/4" impact, 1/2" impact, buffer, inflator, cutoff, and skilsaw, all Harbor Freight Bauer... I also have a corded 1/2" impact, a table saw, and several hand drills...
A deep 10mm pretty much lives on the 3/8" gun.
