I'm doing most of my work with an 8" 4 jaw unless it fits my collets. The 4 jaw has
serations in the jaw that makes it hard to use for small things. I wish the jaws were
smooth.

Then you may want to compare the Buck and the Bison. There are more
and deeper serrations in my Bison 6" six-jaw than those in my Buck 6"
three-jaw. The Buck is an older forged steel chuck, and hopefully my
criticism of the economy Bucks doesn't apply to the current steel
chucks. And, as I mentioned, the price spread between Buck and Bison
isn't nearly what it used to be.

You might also want to keep an eye on this ebay seller's auctions:

They show up occasionally in one of my saved searches and seem to have
good prices on Bison chucks that have been returned or were dinged in
shipping.
