Hector, For tool purchasing decisions I generally try to determine if I will use the tool often enough to justify the dollars spent and the room it takes up. I also try to determine if I do not get the tool how will that affect me.

I have used my 1" impact wrench, and my X12 often enough now to have formed some opinions on both. I originally used only the X12. I used it in lieu of the impact wrench. It is hard work to use it, but one advantage is it works well with a 1/2" torque wrench to set the wheel nut torques accurately.

The 1" impact wrench is much easier to use. It is heavier, requires 1/2" air hose, but it is fast and efficient. I have learned from experience and using the X12 and a torque wrench how much and how to use the impact wrench to get the correct torque. Now the X12 sits in a box rarely used.

Before I invested in the X12 I would want good sets of Gearwrench wrenches and screwdrivers. I would want a clamp on Fluke 336A meter. A Fluke 117 meter. I would want a good set of hydraulic jacks, air over hydraulic. I would want good hand tools for the bus tool box. You see where I am heading. The things I named would be used far more frequently. And I believe I could almost buy them all with the price reduction between the X12 and the $99 Harbor Freight impact wrench.

Right now the X12 is only peace of mind. I bring it with me so I can change my own tires on the road and do not have to rely on anybody. There is some value there of course, but I have also never had an on road flat.
