I come across this on ebay just wondered why it was so cheap ? it looks good but similar washers seem to have around a grand extra on them. Does anyone on here know if this is any good?http://www.ebay.co.uk/itm/13HP-3800PSI-Adjustable-Gasoline-High-Pressure-Washer-Cleaner-Petrol-Water-Pump/253038466316?_trksid=p2481888.c100675.m4236&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D3494bf5e9d934f2ea17a83e611758ea8%26pid%3D100675%26rk%3D2%26rkt%3D15%26sd%3D292142443635&_trkparms=pageci%253Afe6b0059-6ee9-11e7-a27b-74dbd18055b7%257Cparentrq%253A6ab2dd3515d0a9c4d750b874fffa8e98%257Ciid%253A1
