it goes on sale for $69.99 sometimes
thats all i could really remember right now… those are the 2 main ones we use… we also have one of the $10 special impacts we use for smaller jobs… its still goin pretty good
Try Ridgid Tools at Home Depot. They have this one for 159.00. It has 6.2 cfm at 90 lbs. Plus its more portable than the Craftsman.
Welp…I will have to say I was taken care of.
Shot off an email to Craftsman customer service and they responded in hours, saying that the store needed to replace my impact with a similar model or let me upgrade and pay the difference.
The store estimated my gun that came with the kit was on par with the 129.99 model so I upgraded to the Professional gun for an extra $60…the thing is badass too. Not sure they knew what they were taling about, but hey, Im happy 
Score!
Damn, way to go…
Time to go break, i mean use mine…
from what i have seen and dealt with sears every time they get something that is a craftsman that is broken they say go pick out a new one we do and then we leave no hassles.
