I will second rmousir on the red 5 drawer tool cart. The only thing I don't like is that if I put my snap on prybars in the slots on the sides, then the lid doesn't close. Other than that, I am completely happy. I am trying to figure out what to put on the bottom shelf.
The best racheting screwdriver out there is the MAC Overdriver Pro. It has planetary gears that give you four to one output when you want it. Too bad it isn't made anymore. I would go with the snap-on. Best one on the market right now.
If you go to some of the tool websites (Snap-On is where I checked), they list it as "recommended maximum air pressure". I don't think many air tools will "blow up" at 120.
