K'archer makes some good units. Apparently they were selected to clean Mt Rushmore. Stay away from the adjustable nozzles - they don't work for me. I have a McCulloch electric 1600 psi for washing the cars & light work, but I put a standard hose & fixed nozzle trigger on it. I only use the yellow one.
For the heavier work I have a 2200 psi unit from Costco. The gas engine is Honda. I can't recall the actual make of the washer, but I don't see much difference in the way the compressors are built.
