Ratchets or sockets? Ratchets are sized by drive; 1/4, 3/8, 1/2"
Just finished a shade tree brake job yesterday- used pretty much all of my 3/8, 1/2 ratchets. Snap on ratchets sure are nice, but what makes the most difference to me is having a variety of sizes and styles. I used 3/8 stubby, hard handle, and long flex HH, also 1/2 flex stubby and the big long flex.
In terms of value, I appreciate my long flex ratchets the most. I had craftsman full polished tear drop ratchets for many years. They worked fine and still would if I had replacement guts. I had a craftsman 3/8 flex stubby I loved. Tho not as nice as Snap on, shorter ratchets don't need to be super strong or have super fine teeth, just low back drag.
So I recommend buying yourself long flex ratchets. Maybe spurge on soft grip handles. Snap on 1/4 drive, especially the long flex, are also worthwhile, since they are strong enough to pull really hard on.
