Has anybody had any experience with the Karcher, Simoniz, Craftsman,
Husky or Campbell Haufeld power washers?

I'm getting one as a gift for my father, but I'm not sure what to buy.
Anything over 1750 psi costs at least $300 here in Canada, so I was
thinking about getting a new one on ebay -- which means it proably
won't come with a warranty.

Is this a bad idea? Is one brand significantly better than another?
Thanks again for the insight!
