I just went through this search you are doing, before finally buying the 'Subaru' branded pressure washer at costco for $269.99. Anything with comparable specs was $100-200 more, I even saw one of those 'name brand' PW for $800 with even or less specs. Anything more than those specs seemed to be almost double the price, in which you start to get into the commercial pumps. All I need it for was washing the house, deck, pavement, etc. or as we might saw homeowner use.
This thing has done everything I've needed it to do so far, and can't even tell a difference between it and the $2,000 machine I was borrowing from a contractor before. Was I using it for something that would require 5.0 gpm? NO, but that's my point, I don't need it for what I am washing, so why pay the premium price?
I don't know what light industrial use means, but the Subaru unit has impressed me thus far, OH and did I mention, it's electric start?!?
