I have a no-name 30MM impact socket but it's not deep...bought it for the oil drain plug on a Jag I used to have.
Why don't you buy some nice new Proto's? They will be every bit as nice as the truck brands, but new at half the price of the truck brands!
Hit your local yellow pages and look under Contractor tool and construction supply companies. Simply call one that handles Proto tools (most of them do, if not they will handle Williams or Armstrong) Ask for a price quote for your sizes. I think you will be surprised at just how reasonable the prices might be for the individual sizes you need.
Also, you might check over at Harry epsteins website and make sure they do not have what you need.
Anybody have any deep Mac, Snap On, Matco, etc.
Need 30mm and 36mm deep.
