Hello, I am after a new mitre saw for general use, I am looking at the DWS777 but have seen the DWS774 for £110 cheaper, both have XPS and a 216mm blade. The 774 is 1400w and the 777 is 1800w. Will I see much difference? I am trying to buy one saw that will last not another one a year or two down the line. Thanks in advance
