In that budget I would look at Sears rebranding of the Briggs and Stratton pressure washers, as Sears has a great 1 year repair warranty on such things where they will ship it off to be repaired at their repair center. I have one I bought there, replaced once the day I bought it due to a cracked fuel tank, repaired the next spring when it would not idle up / down correctly, no questions asked, turn around time was under a week. That was about 3 years ago, no trouble since then, just used it a few days ago. I do agree about liking Honda engines more than the B&S ones, but B&S also makes pressure washer (I think they bought out some other companies line of pressure washers 5-10 years ago).

p.s. I paid about $190 for mine, end of year clearance deal at Sears, regular price was just under $400, came with the spinning deck cleaner bonus, normally a $65 extra, real great accessory.
