The suregrave is at a dealer who wants nearly twice the cost of a 1640 .I need the work area of a router to cut .5mm sheet brass for making model locomotives. I have better breakout boards and odds and ends from a sieg sx2 conversion I did. Dont really know of any good hobby cnc routers as the market is full of rebadged Chinese machines or overpriced ex school machines.its all abit of a minefield.i dont want to make a machine as my hobby is making model locomotives.michael
