Usually the welding supply has some high quality stuff if you are in a rush. I get all of mine from Mc Master- Carr industrial supply. Very good selection, good prices, Every bit as good (probably better) as the tool truck stuff. It is the easiest place in the world to get an account if you have a business with 3 or more employees. Google them and look at their online catalog. Rutland tool, (Airgas), also has a good selection/price and they offer several grades.
my signature lines...not really directed at anyone in particular..
BE different....ACT normal.
No one is completely useless..They can always be used as a bad example
