Was browsing Craigslist this Morning and found all these tools for 100$, just met the guy, told me his dad retired from Boeing.
I never owned a proto ratchet, feels well build.
I do like that Proto also but it feels like the handle could be 3x as long for the size of its head. The ratchet pawl action feels most precise on those, only thing that comes close in my drawer would be a Wera Zyklop.
