Just bought a Bauer (Harbor Freight) 1/2 impact. You will not regret the decision, but I would have gone for the rigid model if they would have had that deal you posted.
I paid:
100$ for the tool
60$ for small battery, charger, and 1/4" impact (could have bought battery and charger for $40, but for an extra 20$ got the 1/4" impact)
40$ for the large battery.
I already own rigid tools so this deal would have been sweet. As it is I am pretty happy with the Bauer so far, it has done everything I've asked of it except for axle nuts on the wifes Mazda 5. For that I got the air out.
Already looking up the return policy at harbor freight!!
