There are some good tools there and they also sell some very low end stuff.
I agree on the compressor, buy a 20 gallon, but look at the recovery rates. You will want soemthing that has good recovery.
Skip the 1/2" air ratchet..it'* slow and has little torque. Use an air gun for 1/2" stuff. Call me tonight and I'll check if I have any coupons from them and forward them to you.
On the air gun.. go for 500lbs of torque. It'* important taking HB bolts off.
I'm not a fan of the wobble extensions. You can slip or wobble when you need to a good connection. The longer an extension or the more play in it..the more torque you will lose between the gun and the bolt.
