I have an Iwata HP-C and a Revolution CR. The Revolution has a .5mm nozzle and puts out more paint than the HP-C. I usually do about 90% of my work with the Revolution and 10% with the HP-C. The Revolution can handle most any type paint. It will handle everything short of very fine lines. I am Happy with mine.
The SAR is not a gravity feed but a siphon feed. It is intended for larger area coverages. The CR is a gravity feed and intended for smaller areas due to a smaller paint cup(1/3 oz). Greg.
