Unless you work in a shop, Snap-on is hard to buy, much less get replaced under warrantee.

I did buy a 1/2" opening 3/8" drive crows-foot from them after breaking a Craftsman. I needed to use that for 40 ft-lb of torque, and the Craftsman broke on the first job. A piece went flying across the garage, and I was quite glad that there wasn't a car (or part of me) in the way. I did get it replaced by Sears, but didn't use that one for that particular job.

It was a royal pain to buy the Snap-on part. I had to go to a shop and wait for the van to come. If you work at a shop where the van comes, they're very convienent. If you don't, it's very much the opposite. My time is much too valuable to wait for salesmen to show up.
