My son and i are about to embark on a couple of largish tiling jobs, His kitchen floor approx 25 square Metres and my bathroom approx 20 square Metres, using 400x600mm tiles in the batroom and 300x600mm tiles on his floor. So we were wondering if its worth investing in a tile saw and if so which ones are recommended, or would it be wiser to save our money and us an angle grinder..Cheers in advance Bill
