broke 2 spanners and a socket wrench on a nut on the suspension so i was like "f*k this i'll get you!!!"
drove down to supercheap, picked up a 2hp comp. and tool kit, got home and fired it up. took a little bit - like about 20 seconds of "blat-blat" - and the sucker was off!
now every time i work on the car the first thing i do is fire up the compressor. lol
best investment.

Compressors and tool kits are best left to experienced mechanics who know the approximate amount of force to apply to each different bolt on the car. E.g. Each bolt on the car has different tolerances and re-torque specifications. You could either break a bolt causing it be stuck, or not tightening it enough for road use.. (correct me if i'm wrong.. but u can't measure torque on a air gun or whatever u call it)
p.s: Not implying that anyone don't have the experience.. some people do..
With torques and air guns, claymore is right.
You can purchase whats called a torque stick. We have them at work, they are a like a real long thin socket. They are supposed to work by reducing the torque (via the distance and/thickness of the stick i'm pretty sure). They are pre-set at a certain torque, ours are 135Nm and used for wheel nuts. I have used these before and checked the torque and they have been up around 160NM so they are not all that accurate. I'd be guessing the power output of the compressor/rattle gun would have a bit too do with it as well.
Rattle guns have there uses. I rarely use them even at work, i do use them for removing wheels and a small amount of other things. There is a feel to them though. I reckon if you had an old-timer mechanic and asked him to tighten some bolts to certain specs by hand and you then ran a break-away torque bar over them you would be surprised how close to spec they would get.
I removed my crank pulley and axle nuts with a sidchrome 1/2" breaker bar and an extension pole.
Sometimes if a bolt is really hard to crack and you cant get an extension on it, you can get it off with shock by hitting the spanner with a soft hammer. Not the greatest or recommended method, but it can sometimes help. You risk rounding the bolt/nut. Edit: do not attempt to loosen your axle nuts this way. I wouldnt use it on something with that much torque. More for something you cant get a breaker bar on which would normally crack it reasonably easy.
Most if not everything can be done without a air compressor for the DIY mechanic tools at home.
