Craftsman (Easco/Danaher) round-head-fine-tooth (RHFT) ratchets are great ratchets, and often go for well over $100 on auction sites, especially the flex heads if you can find one. Complete sets also can fetch a pretty penny.
The RHFT wasn't exclusive to Craftsman, but they are more sought after. Other brands include Proto, SK, Allen, New Britain, etc. They have a dual integrated floating pawl design that doubles the number of clicks to the number of teeth. You get the strength of a 45 tooth ratchet but the 4 degrees of travel between clicks of a 90 tooth ratchet. The darn things were very reliable. I've picked up many that are several decades old working just fine without any hint of a drop of lubrication left inside. Dry as a bone, as they say. IIRC the 1/2 are 45 tooth, the 3/8 are 41 tooth, and the 1/4 is 35 tooth, and they had 3 tooth engagement for each pawl.

I love mine. Still use them all the time.
