My long time favorite is the classic SK 45170 round head 3/8" drive ratchet, about 40 teeth, no quick release, about 7 1/2 in. long. It is smooth, very strong, low back drag and the standard length handle seems to fit anywhere. Thanks to a couple of lucky, cheap finds at garage sales and the flea markets ($5 each!), I have several. After a cleaning and a light greasing, they work great. New ones are $60-65 everywhere.

My current favorite is the Harbor Freight Pittsburgh Pro 3/8 in. quick release Swivel Head Ratchet ("roto ratchet"), 72 teeth, with the green cushion handle, about 5 1/2 in. long. I like the flexibility of the rotor head. Also, I tilt the head straight up and spin off bolt heads and nuts off just like having a socket on the end of an extension. This ratchet has a shorter overall length, but it fits everywhere. Back drag is higher than most, but it works well. I think I paid less than $15 for it, so the price was right for me to give it a try, since I had never owned a swivel head or "roto ratchet" before this one. In fact, I liked it so much I bought the longer handle version, about 9 in. long. I don't see the short handle version on the HF website, but the longer handle version is now $16.99.
