When I transferred as a mechanic at the tool store, I went to harbor freight (even though I had a pretty good tool set) I dropped around $600, and that got me a nice sized toolbox set, a pretty full mechanic's tool set, a multimeter, and a couple of air tools... I think I got an air drill for $6, a 1/2" impact, and a 3/8" air ratchet for $39, a die grinder for $16, and a cutoff saw for $6, and a little chipping hammer I call the "angry mosquito" for around $9. Every one of the air tools, even though used pretty often, are still around 2 years later. Not one problem. All the air tools held up to my rough hand. Some of the other tools are utter crap, but they did give me my start, and I began replacing them as they broke, with better stuff (Craftsman and snap on). Harbor Freight is great, as long as you keep in mind it's cheap stuff for the most part. I wouldn't think twice, however, about buying air tools from them again.
