My big Snap On KRL 1003B work box was bought new in 2003. I have a KR 537 that I bought used in the mid 90's. It was the first box that my dealer ever sold when he started in the business in 1976. I have a Mac MB1500 that I bought used in 1995. And I have a Craftsman 12 drawer top chest and 12...
I've actually asked my Snap on dealer if the tool manufacturers and the hardware industry have a conspiracy. Once you have a complete set of sockets they come out with a new head style. So you start over buying a new socket or driver set..basically the circle of life..lol.
I have the OTC bar like that one. I use it for suspension work mostly,but it does come in handy in other applications. Just remember.."Leverage is your friend".
