Most bodymen use air tools. For the hobby guy, there's nothing wrong with the less expensive brands, but don't expect as long a life from them as name-brand tools. More important (critical, actually) is a good compressor with at least a 5hp pump, and a 60-gallon tank. Look for at least 11 SCFM (air volume output) to be sure your compressor doesn't run all the time, which causes moisture to build up in the tank and lines. Said moisture will contaminate your tools, project, and break your heart when the dreaded "fisheyes' show up in your final paintjob.
