Need a small compressor to blow out the filter on my Oneida, also to use small air tools like a brad nailer. In the past I always bought the larger compressors thinking I would take up spray finishing but it never happened. And now with the small shop dont see it happening again. Need to be able to put it on a high shelf is possible, as space is at a premium and am concerned about the noise. Was looking at the ones at Harbor Freight this morning. Are they junk?
