I am looking to buy a pressure washer to clean basic items around the house (Eg: siding, fence, patio, etc...) I looked in the Home Depot who has an ExCel model with 2400 psi, Honda power and then I looked in Lowe's at their 2400 psi model by Generac also powered by Honda. Is one better than the other or are they the same? Excel is 397.00 and Generac's is 425.00. Price is not the factor by which I want to make my purchase. Any advise???
