This compressor is a great value.  It has a quality oil lubricated motor and is competitively priced with "oil-less" compressors of similar size and capacity.  It works great with my various small air tools (palm nailer, impact wrench, etc).  My only complaint:  After a few hours of light use, the regulator dial became very hard to turn, and eventually stopped working altogether.  I dismantled it and found that the dial threads had stripped.  I replaced the regulator with an inexpensive AmFlo model purchased at Lowes, and am much happier with the new one -- easier to adjust, more precise, and more accurate.  If Hitachi included a better regulator, they would have a 5 star product.
