Klein, Proto, Crescent, Gray Tools. All nice, but usually $$$$$
TSC and Home Depots around here sell a 16" "Dewalt" brand for $40. I've seen a lot of millwrights and ironworkers with it in their box, and they seem to like it.
I picked up a 12" "Titan" brand from Princess Auto a couple weeks ago for $11.99, And for the price, I can't complain! It'll be used as a spud, a bull pin, and a hammer, and I don't care!
